No luck.
I tried loading a map and typing in the commands. No bueno.
SO I loaded another map and got some error messages because I was access level 10.
Still nothing. Tried another cave map. Nothing. exited and tried again.
Interestingly, I loaded Pocket D and the map fog was there! Also, as I moved it cleared as per normal. All fog cleared with /nomapfog 1.
/nomapfog 0: restored the fog!
My guess is that Pocket D is zone Map, even though it looks like a mission map. The Zone maps worked exactly as you described, but the mission maps, no.
Whenever I loaded a mission map I got errors saying:
File: maps/Missions/abandoned_tech/Abandoned_Tech_30/Abandoned_tech_SM_30_Layout_01.txt
Last Author/Status:Perforce.cpp failed to connect to Perforce.
No loading screen match found!
I'm wondering if these mini's fail to show up because they are constructed by the mission authoring system and since that is disabled/unavailable, no map.
