After taking some time away from GM to watch Fear & Loathing In Las Vegas (was thinking of Rango at the time and it gave me the urge to watch Fear & Loathing again), I checked on my help request on GMC. It was pointed out to me that deactivating instances is a bad idea in a Room Start event.

So now that that's taken care of, I got to work on cleaning up the program a little. And in the process I discovered that you can include comments in constants! So I moved a couple global variables into the constants list and gave them descriptive comments.
