Hey Klaw,
I tried out the map, the finished bits look very good! I like the industrial/craped look with the tubes running everywhere and the ENT style layout really fits the era.
Apart from the obvious bugs you already mentioned, i did encounter 1 serious bug but i couldn't really reproduce it, though it might still be worth looking into.
I was in sickbay, stepped into the turbolift, used it to go to deck 7, i then turned around to the door, which closed, but behind the door instead of seeing sickbay i saw the "Hall of Mirrors" effect, and my EF crashed to the main menu. I forgot to write down the exact error unfortunately and like i said i couldnt really reproduce the error. I'm guessing it is a small glitch with placement of Areaportals around the turbolift doors, so it would be good to check those.
Anyway, so far, looking good!
