Hello, I'll present the context:

I'm at war with "purple", who at the same time is at war with "yellow". There is no alliance between "yellow" and I. 

"Yellow" start to siege a "purple" city with 3 of my armies nearby, and they end up getting locked into a battle in wich the own battle preview says I'm not involved.

I have something similar though a little different. I just finished a war with "purple." One of my armies seems to have moved into a siege that was far away, and perhaps started by "black." I cant click on the preview, but it doesn't prevent me from moving through new turns.
