Hey guys, I fixed both the settlements in the campaign and in the custom battle menu. I used ITWE and I applied the same changes that were done on the Minas Tirith settlement, and it worked! I haven't tested all the settlements in the campaign but all that have been reported as crashing should work now. To apply the patch, download the two files listed and replace the according folders inside the settlements folder of the TATW mod. Let me know if this fix work for you guys too. It should work for Linux as well.
