Trying to figure out if it's a bug or something we can fix.  We like to play our MP campaign battles on mutual slow speed.  But lately in ambushes and some siege battles the game doesn't recognize slow speed it just treats it as paused.  Anyone else have this problem?

I have this is every co op campagin I play. It really sucks. I don't know how to fix it and every time i google it or ask on reddit people just say "turn battle realism off" but it never works.
