Two issues:
-The lighting could be made slightly brighter
-The doors
On my local dedicated server, i have no issue with the doors, however, on my server host, the doors are buggy. They get stuck on players (while going up), and so this makes it a lot harder to play the map. I don't it's an addon causing it (there aren't really any).
Can you fix this/do you have any ideas as to what might be causing it?
You have your tickrate set to 100 change it to 66 (orange box default). We had this same issue as well. Having it set too high will also make rotating doors open slowly.
