I am SO confused. What the hell happened??

[catch_22 4]

After playing like 4 hours straight, dying a bunch, I finally found a barn with a shotgun and a crossbow. I tried to pick the shotgun up, and dropped my hatchet. So I then picked the shotgun up, opened my "bag" and tried my absolute best to figure out what the hell the terrible inventory management screen was telling me. I clicked "Add to bag" or whatever, because that's where I wanted my shotgun to go. Well, wouldn't you ****ing know, the gun just completely disappeared. So I settled for the crossbow. And in the tangled madness of whatever the developers call an inventory screen, I managed to get the CROSSBOW to disappear too. What the hell did I do? They weren't on the ground. Just gone. I had finally started to have fun and I somehow managed to delete items. I JUST WANTED THEM IN MY BAG.

It takes 10 slots to hold a primary weapon (shotgun/xbow, etc) and 5 slots to hold a sidearm. Right now, if you don't have room in your bag for what you put in it, it tosses it into Limbo. Your starting Coyote Pack only has 8 slots when completely empty, so any primary will vanish on you.

This mod is in Alpha, and it is kind of buggy. Bugs are being fixed, even though this IS Alpha (when game mechanics themselves get tested/storyline/new content), while Beta is for bug fixing. Rest assured though, your problem is on the fix list in 1.7.2, and will be fixed. Check for "Items Disappearing" on the forums/bug list.
