Frozen Monsters That You Can Not Kill

[Hatchet]

There has been several instances while playing a level where there would be 1 monster that you run into that was just frozen still, you couldn't target it or kill it. If you killed all the other monsters on that level, you couldn't advance to the next level, since the 1 frozen one is still left. Only way out at this point is to exit the game.

When I say frozen, I don't mean the frozen spell cast on the monster. I mean frozen, as just standing still.
