Level doors problem

^Did that, still no cigar.

Edit 3: I solved the problem, but I don't know how. I think it's an issue with the OSX system itself (I'm modding on a macbook pro). I loaded up the exact same custom story on my windows 7 laptop and I had absolutely no issue either. The strangest thing is, after adding some entities in the map on windows 7 and then transferring it back to my mac, it worked completely fine when I played the map again in OSX. It's as if the very process of accessing the map in windows remedied the problem.
