My game crashes whenever I try to start a siege battle on the battle map as the Areuakoi. Auto-resolving works fine, as do live battles outside of settlements. This seems to happen only for the Areuakoi, and only when a settlement is involved - in one attempt, I was besieging Iltirta and was attacked by a second rebel army. Tried fighting on the battle map and it crashed. Which city it is doesn't seem to matter, either.
Attached error log is the result of an attempted siege of Kontrebia.
Any help is appreciated, thanks!
