Dunno if these have been listed already, but i don't have the time to sift through to see.
What i have experienced so far:
1) Sound stops working in Tactical battles except for music. No attack sounds.
2) Tactical battles will become non responsive. For instance, I had a summoned bear who was right next to an enemy. The icon would change to an attack icon but when i would click to tell him to attack, he would do nothing. I culd click on the munu command icons and the would respond. But I couldnt click on another unit to select them, couldnt tell him to move, couldn't do anything. I could, However, click the auto resolve button which is what I had to do to get out of the combat.
