I don't know why but when i use this skill rarely the game will hang. The game music is still playing but the game can't be played. I get the usual options for an app hang on windows: wait for program to respond, close program, etc. This happened twice already and it always happens when i throw it and hear the bottle cracking noise, then the game just hangs. I may be conjecturing here but i think it only occurs if the game attempts to autosave as you use this skill.
This is a known problem. I think it has been fixed before, but came back and is actively mocking Nicholas for trying to fix it. Do not worry. It will get fixed.
