Platform: Windows 10
Mods: I noticed it first with mods, ran through troubleshooting, removed every mod except long war, ran through it again and still had the problem, so this shouldn't be the cause.
When I try to send a squad and want to add a soldier for one reason or another, the UI disappears entirely, the escape menu doesn't pop up and it is impossible to go out of this screen once you have it, forcing you to alt tab and close the game that way.
Screenshot:
The game is stuck like this, after I pressed select soldier on an empty soldier spot
Additional notes: I noticed this bug come up yesterday, just after the 1.1 update, and because steam workshop doesn't allow me to roll back to a previous mod version, I'm inclined to belief that the bug is in this update.
thanks in advance!
Edit: I forgot to mention that it happens on every save, I've made 4 saves, all of them had this bug, I play on normal difficulty, no ironman mode with beginner VO reduced and subtitles on.
