[X] Ground enemies fall to death when past level splitters.

[Triple J]

Whenever a ground-bound enemy walks past a level splitter, it'll fall down completely. This is because ALL TILES too close to or past the side of the splitter opposite to the one the player is in do not exist at the time. This isn't always a problem, but if you're fighting an enemy close to a level splitter, the battle could be abruptly interrupted when the enemy decides to pass the level splitter from your side.
