My friend and I who both play this game are both experiencing frequent crashed to the main menu during our campaigns. (we both are playing separate games but are having the same issue).
The crash goes like this, we either just finish a battle then click continue and it takes us back to the main menu meaning we have to repeat the battle.
Or we try to load up a save game and it takes us to the main menu as soon as we get in.
Have tired verify game cache which lets us play 1 or 2 turns more but then the problem repeats. very frustrating, Any permanent fixes?
