The game often gets stuck in battle against a frostdevil when it casts barrier.
The frostdevil casts barrier and I can't do anything anymore, the game gets stuck on this spell, the word "Barrier" doesn't disappear and I can't do anything, I have to force close the game with Alt + F4, launch it again, and reload my last save in order to continue so I came to save every time I see a frostdevil because this annoying bug completely breaks the game.
