Build 41: If you're experiencing disconnects/CTDs when attacking bandits, I tested it for some time this afternoon and found that it always happens if the bandit is wearing a bag. When bandits with bags are killed by other bandits or zombies, their corpses appear naked. Unsure what causes this, or what mod conflict it could be (I have too many on my dedicated server), but I solved it temporarily by using the in-game admin Bandit Creator to strip the bags from all bandits that have them.

EDIT: It's all three tiers of the white AuthenticZ duffel bags. They don't have textures ingame, and for some reason they're pulled as the default bag for most of the bandits. I changed all white bag-carrying bandits to use different duffel bags and I'm no longer having issues attacking them.
