I've been having this weird bug

[Castle (DayZ) 23]

After awhile of being on (fixed through abort > reconnect) my framerate will drop to half, zombies will be unable to detect me no matter what, items will be really slow to move in/out of my inventory, and I am nearly invulnerable.

Nearly invulnerable as in: My aim is not affected by pain, having a broken leg doesn't stop me from running, I can't bleed, and the only things that have given me "death" in that state were two people spamming M14 shots at close range and one guy hitting me with an AS50 multiple times. It doesn't give me the "You Are Dead" screen, my character just falls over and becomes uncontrollable. And my blood doesn't change for me. However any damage I take like this will affect me on next login, so if I get shot a few times I'll be perfectly fine, but a fresh spawn on next login.

It started after installing Namalsk, reinstalling didn't fix it in the slightest. Removing Namalsk changed the time I have to be playing for it to start from ~10-20 minutes to ~50-70 minutes.

And I don't really know how to describe it as a bug report as given that none of my friends got it from installing Namalsk I have no idea how to repeat it.
