ToME: the Tales of Maj'Eyal

As a dwarf I used the lightning form to get away from the boss. During my escape he used his blinding skill, but I used the map to guide me to the portal. I don't remember if I reached the iron council in lightning form or not, but after that every time I used the skill I also couldn't see anything(aka being blind, but without the blind debuff).

The problem lies in the fact that now, even after deleting the game and the "c:/../user/te4" folder, I still get blinded when using lightning form. It happens no matter the race.
