Minecolonies version

version 0.8.7613

Expected behavior

not to crash when upgrading building

Actual behavior

client crashes when clicking upgrade on citizen hut 4

crash report: https://gist.github.com/Faenum/d21b2a5163d2483206d0f098b38ceb2a

Steps to reproduce the problem

Tested on a second hut, same problem, upgraded to level 4 then crashes on next upgrade

Would this happen to be related to the Medieval Oak level 4 -> level 5? If so, we recently had a fix for it from the creator and should have it in the mod soon.

Yes, thats the one. Brill, thanks.

Yeah fix is ready, will be included in next alpha
