Beware of Bad North's game-breaking bug

Bad North has a particularly nasty bug that appears to happen at random. For some reason, you might experience a level where an enemy doesn't register as killed. This means you're stuck on the island, as the game thinks there's still an enemy for you to defeat. If you decide to abandon the island, the game ends up crashing. Even worse, this wipes out all the progress you've made.

There doesn't seem to be any comment from the developers on this bug just yet. Hopefully they have been made aware and will whip up a fix soon.
