Changing/inconsistent bloodtypes

[Kerwyn 77]

Couldn't find any other topics about this, so sorry if it has been posted before, but I came across something intriguing today, and thought I had best share.

 

As my squad's designated medic, it occurred to me that with the saline nerf incoming, I had best start practising with blood bags so I'm not stuck fumbling when my team mates go down. To this end, I've been playing doctor with my squad figuring out blood types and compatibility, and the best way to not accidentally kill my friends. This is where I ran into a snag.

 

On a hunch, I tested myself again today, and while two days ago, on the same server, and the same character, I was B+, now I'm O+. I haven't found another test kit yet to see whether or not anyone else's, or the bag I took back then has changed randomly, but this is distressing news regardless.

 

What this essentially means is that, despite all my careful preparation. My first aid load-out is essentially useless as I'm going to have to lug around a bucket of blood testers alongside my other supplies just so I don't accidentally fill my mate up with his own blood only to find out it's now magically incompatible.

 

The problem here is that I find myself torn. I'm fairly certain blood types aren't supposed to change (Although I sure hope they are randomized at respawn,) but now I have an added level of intricacy to my craft, and that is awesome. Blood testers are something I never seem to find, and they are single use, which means their value to me suddenly went through the roof, this excites the collector in me, while at the same time adding an extra layer of stress and adrenaline when I get in a tight spot, as I -really- don't want to lose the stuff in my bags. 

 

In short, I'm fairly certain this is a bug which may need fixing, but part of me likes it, and this bug is making this medic's life far more interesting.

 

For discussion value, has anyone else come across this? Perhaps someone out there has harder evidence than my anecdote of "This one time, in Novy Sobor."

Well, this one time, in Novy Sobor...

My friend blood bagged me with my own blood from about an hour earlier. I died. 

It does seem random sometimes. Good thing you brought this up. I had just thought that maybe he had used his blood on me instead.

I've only noticed blood type changing when I get a new character, interesting tho have to see where this goes, I hope this bring back for formal banditry, as opposed to the KoS "bandits"

I haven't been cuffed in so long...

This would appear to be a bug. Blood types should only change upon respawn.  People don't spontaneously change blood type IRL.

[Korsbaek 1778]

I hope you've reported this :P

[slizzedy 70]

So if this gets fixed, should every player have the same blood type on different characters (you could use the GUID to calculate the bloodtype, so it will never change), or different bloodtypes on different characters?

 

Having the same bloodtype would of course make it easier, and you could quickly get to know the bloodtypes of your mates and who is compatible to who. Having different bloodtypes on different characters would make things more complicated, but more realistic if we assume you are a different person after respawn.

If you die and come back then it's understandable that your blood type would change, your a different person.

[Problematic 71]

I think it should stay different each character, your new guy isn't your old characters long lost twin or something so it wouldn't really make sense that all your characters have the same type, you're just starting on a new person. 

 

Also it would make blood type testing kits redundant for people who had the luck to find them once on a character.

I'm O- and I have healthy status.. If you want to meet me on a server and collect 3-4 bags of my blood, send me a message thru the forums and we'll work something out.

[Kerwyn 77]

I hope you've reported this :P

I reported it last night. Made the forum post first though, I wanted to get some confirmation that this was actually a thing happening and not just me being crazy. Thanks for the tip anyway though.

[knar33 158]

I had tons of type o- blood bags drawn from me and gave out around 10 of them, never had a patient negatively effected by my blood.

 

If you die your blood type changes, and you have to be careful if you have more than 1 type of blood in your inventory. Thetop-leftmost blood bag in your inventory slots will be used first, no matter if you dragged each blood type to your inventory individually.

OP, I suspect you are mistaken.

I had one character that was alive for several days. In the span of those days, I found 4 or 5 testers, and I used them all. Across different servers, different log ins, and different days, with the same character, I consistently got a message informing me that my blood type was o+, every single time.

My input.

You may be wrong. You may be right. Either way, we are all doomed....

[somethingbloody 118]

I think blood testers should only be used for testing blood bags you find and the blood of unwilling "donors". I don't think its too much of a stretch to assume that survivors would know their own blood type from before the apocalypse.

[Liege 70]

I'm 32 and have no idea of my blood type. Never needed to know.

O- is the universal donor

[Zedicologist 162]

well i will have to try this out.  Hopefully this gets figured out pretty soon cause that would suck.

No, you will still have a different blood type for each new character.

This is interesting, this means that the bug might not be universal. I will confess my tests of this have been extremely limited in scope, only testing myself twice, with a lot of possible variables mixed in. What I can confirm, from my own handwritten notes, is that over a period of several days, my character's blood type changed from B+ to O+, And that I have not died in that time. Unless damaged blood testers give off false readings (Which would be awesome, come to think of it, that should be a thing if it isn't) there is no way that I am aware of in which the fault may lay with me.

 

What your tale tells me, is that the change is triggered by something, an event or specific criteria, which I triggered, but you did not. sadly, I have too little information to go on right now to even begin to form a hypothesis on what could cause it. As I said earlier though, I am continuing my tests, and hopefully I'll find out more to post here in the future, Hopefully Berezino is quiet tonight, I need to find more test kits.

You'll have to tell me what you find out,the more information we gather on the bug, the easier it'll be for the Devs to find and fix it.

Those testers are WAY too rare in my opinion right now, especially now when saline gets nerfed

If you think blood testers are too rare take a view of these videos, they are rather balanced considering the current blood mechanics

O- is the universal donor

That was the basis of my post, I was type o- and it never hurt my medical patients in my many medic runs. That doesn't necessarily prove my point, but makes it highly unlikely considering the amount of successful o- bags I've delivered without an issue Edited January 21, 2014 by Knar

It may be worth considering if you made a mistake before forming a hypothesis. Eliminate all variables, then come back with some results :D

We must first see how much the Saline bags gets nurfed.  The notes say they won't give you back all your blood anymore and I think they left ir vauge for a reason.  My guess is that it will still be more effective and safer than a blood bag but we'll have to see.  Even if they nurf it down from 5000 to 2500 that is still a huge nurf while still making it a better choice than a blood tranfusion of 1000 blood that can potentially kill you.  First thing i'll do when the patch comes out is fill 4 blood bags and then get someone to IV a saline bag into me and see how much of my colour returns for a rough estimate.
