Crash Log

I was in a village trying to loot a chest (I have a mod that adds additional buildings with chests to villages) using shift-clicking, and got this crash.

Sorry for not responding in a while.
I just looked into this and fixed it.
Unfortunatly this is only a temporary "fix" as the ItemPickup feature is far from being finished (need to figure out a good way of implementing it)
The update will go online with the next version (which will probably just add free scaling and the 1.12 version port)
