Hello, near month ago I played with skavens and in one moment desapeared button "use" in all spells and abilities. I tried to reinstall game, but situation was same, I thinked that it was temporally problem. Today I decided to play again, chose undead and in tutorial mission sow the same - I steel can't use any spells. When I choose spells, it have only "close" button. Can you answer me, what I may to do to escape this error?
