Minecolonies version

Version: 0.11.932-ALPHA

Expected behavior

No crash
+
second problem : my 2 builders have bot issues with the request system, and with their own inventory/hut inventory (when dropping an item in it it's not recognized)

Actual behaviour

crash
+
builder never being delivered by my deliveryman

Steps to reproduce the problem

wait for a building to be constructed, it doesn't happend everytime, tho the 2nd problem (not the crash) happend a lot since 4 days (I try to keep up with each important alpha - useful bugfixe -, might be related to a change in one of them, didn't had this behaviour 4 days ago)
