I checked the description and it already had the map name. Though I did change it to as follows
" (2-4) Night Drop ", and added a small description. Not sure I totally understand option 2, but option 1 didn't work.
Ive made a custom map and saved it to the correct path (c\programfiles86\steam\steamapps\companyofheroes2\coh2\data\scenarios\mp,or something along that line)
When I hit export it says its saving it to c\documents\my games\company of heroes 2\coh2\data\scenarios.
After loading up the game, it doesn't show up in either the custom game nor the modding hub.
