I posted the crash file over here:
http://www.minecraftforum.net/forums/support/modded-client-support/2778061-1-10-2-self-modded-crash-exception-in-server-tick#c2

If i should paste the code here, feel free to tell me and i will do.

Fix will be in 3.1.4.0. For some reason the entity villager that Agricraft adds doesn't have an internal name.

Release with fix now on CurseForge.
