Hi,

We really love this mod but it almost always crashes when we ask a villager to create a farm. It does sometimes work, but mostly we get the crash. This is true for the 1.8 version too.

I had just Radix core, MCA and Biomes O Plenty mods installed and the forge version was: forge-1.8.9-11.15.1.1731-universal.

Here is the crash report from a 1.8.9 server.

ey i have the same issue will this be looked into?

Better re-open this.
Same results, different cause on 1.10.2

Figured since it was the same result, I should post here instead of creating a new issue.
Stupid auto-forum isn't very specific on criteria.
