When a map is voted on, the settings i have in server.cfg are ignored...i know that i have to put something in my default.cfg, but what? When i just put the settings nothing happens.
server.cfg is executed only once by design (and maprotation.cfg settings aren't executed on mapvotes). you need to create a folder in base called something like mapconfigs, and set g_mapConfigs to the name of that folder. the file called default.cfg in that folder will be executed at the start of every map, followed by <mapname>.cfg if it exists.
