HolyHall/Twilight Temple Issue

My mobs are hiding in the floor :p I read somewhere that I need to replace the map with one from the original ENMY 1.3.6 version for it to work properly (I'm using Hrace's server), but am not sure which files to upload to the server, or if there are any other modifications to be made. I've done a search, but just ended up more confused than ever :/ Thanks for any help.

*facepalm* I always do this, ask for help, then manage to fix it sraight after :/ Copied original server map files for Holy Hall, but kept the precint.sev and regional.sev... it now works perfectly!
