Siege crash on campaing map

In every siege in the empire provinces (Brass Keep, Middenheim, etc) the game crashes with no message after the bar loads(I play as chaos). In norska the sieges didnt crash. I reinstalled the mod and validated the game on steam, it fixed the problem for a few hours then again the game started crashing again.Although custom battle sieges play fine.....

being fixed in next version

Is the custom siege battle thing a good workaround for now tho? Im just coming back after a few months and this is the bug that made me quit playing.
