Hey,
I believe that the rcon map command for the Modern Warfare maps is wrong.
I've never played it myself but I checked the file and I think it shouldn't be:
"map mw_docksunset"
but
"map dm/mw_docksunset"
Same for the other dm maps, and ofc. ''obj/mw....'' for the objective based maps.
Couldn't find any script (or readme) where it changed this.
Greets,
Brian
