Haven Campaign Mission 1 done, but campaign does not countinue.

[Rineum]

I just played the first mission of the Haven campaign and went back to the council after it was finished. Now fpr some reason i'm not able to continue tha campaign since it continues the first mission automatically, without any enemies left and all missions cleared. If i try to end the turn, the yellow UI turns starts, but nothing happens. It's a gamebreaking bug for me, how to fix it?
If I try to reload the save state right before the "final battle", the game crashes.

same problem for me. I did the final battle and the game just switching turns all the time til I get bored and leave . 30min it lasted.
