MCA 1.7.10 Crashing?

Hello, everytime i use MCA (Minecraft comes alive) when the zombies attack villagers sometimes they turn infected but then most of the time it crashes me? I think the default villagers infect status messes with this but im unsure or even if possible to disable. Im useing the latest forge and MCA right version. It also works fine with mobs turned off but when mobs are turned on.. Link to pastebin in spoiler
