the other night i tried to make a 7v7 map and it crashed upon opening. when i removed players to make it a 12 player map it worked fine. as far as i know i had the yaml file correctly written and enough spawn point, but it dident work with 14 players.
another thing i think openra should be looking at is a choose start pos, much like what they use in ta spring. the host makes boxes for each team to start in. has more options and is more usfull. you dont run into the problems of wanted to do a 4v4 on a 2v2 map
