Well, i just spent a fair bit of time making a new template game and moving things over, to see if i had buggered up some code not in the room scripts when i was playing around. Still can't enter that room. Had a look at the memory usage;
Free Heap : 17782
Largest prt: 17808
Guessing i'm fine with that for the moment as well.
*EDIT*
Well this is a little embarrassing, for some reason my room pic decided to change the whole rooms control to white, even when it said it was turned off, so problem solved now...
