Here are some bugs I found during some battles, And A few out of combat.
1 - A part of my army is uncontrolable and get stuck after they try to enter the enemy fortress trough A siege ladder/Siege Tower/ Or just trough the main gate.
2 - A few of my soldiers/workers get stuck at A edge of A mountain or cliff and cant move anymore.
3 - The Castle wall stairs is not working properly, If soldier walk up the stairs some of them teleport up the wall, Or move like A evelator up the wall, In any case they dont use the stairs that much.
4 - My hero cant move trough Dagbor anymore after I talked to A merchant.
This are the bugs that I encountered so far.
