Wall triggers blocking off level segments

[MicroChasm]

I got into a situation where I stepped on a wall trigger and walked through the area now opened where the wall was. A golem came after me and triggered the plate again, closing the wall. The segment of the level that I was in was closed off from any other segment, so I ended up being soft locked.

The level generation should probably do some type of check to make sure that this doesn't happen.
