@Raycoms what's the eta on the fix?

Will rolling back to a previous build even solve this problem?

do we know which schematic tho?

the miner AI is causing it

Someone scanned in an entity with a schematic

What seems to be the problem officer? Your back tail light is out... we dont load broken stuff :P Entity Vehicle is getting a null pointer exception? is that normal?

at com.minecolonies.coremod.entity.citizen.EntityCitizen.func_70636_d(EntityCitizen.java:1068)

line 1068 of entity citizen. Whatever that is doing is the problem

is there a way as OP to force load the schematics into a world?

wait wait wait

are schematics even supposed to have mob entities in them? if that was not ever the plan, can't you create code that sanitizes the schematics on load, ie removing mobs.

However, back to the first question, if that's possible I'll commence to doing the work of finding the bat in the belfry.

I'm pushing a workaround for this.
