Im not to sure wat you are on bout but what i do is:
1. make map with doors in.
2. put map in server directory
3. open up mapinfo.txt
4 put in map, e.g i call the map BT123 i write [BT123 <ingame map name> 0]
5 then i make doors link to other maps or the same one like, u would put this again in the mapinfo.txt, like this:
BT123 125,16 -> AD345 18,19
then i have the door lead back to where it came from buy putting:
AD345 18,19 -> BT123 125,16
then wing the map in a client map folder reset server go to the map and the door will work.
hope you can understand that.
