It happens before fights start,well i checked it again and it seems that it only happens when Edwin goes first into a dungeon(apart from the rest of the party) into an unexplored territory(black) the area doesn't reveal as much as it should and ism forced to click every sec to make him move again and reveal a little bit more.
Edit: Found out that Edwin gets close to an enemy(touch-range) to do a spell which doesn't require it(Chaos,Cloudkill etc') any ideas?
