This was propably asked a hundred times before, but this bug is really a game breaking for a mage-oriented characters. When casting something on a spell with a left mouse button it seems to stuck and never release it at all! The spell is stuck in non-released state and is basically useless. The bug has happened after i have equipped a staff that had a fire buff, but it didn't shot a single fireball, just a simple "magic" sphere. Now the similar buff effect happens even on a non-buffed staffs too! This game has just several buttons for skills to please the console crowds, but getting that number dropped by a third? That's a game breaking bug for sure. What have i tried before: searching the net ( steamcommunity.com/app/367500/discussions/6/451851477882517413 comes first), reloading from a checkpoint, killing yourself, resurrecting yourself, giving the staff away. Didn't try to load from the backup, because it took me too much time to notice the bug.
