I am playing the campaign and suddently (in the 3rd scenario of the necro campaign) in a battle a timer appears. I have set game setting to standard, so that no timer should be used. I have not recently patched the game.

As I like turn based games, I dislike timers (why not go to the toilet while playing etc.), so I do not understand the need for a timer in single player games.

Does anybody know how to get rid of the timer?
