I have the PC version. I boughtthe DLC 1 and the DLC 4.  When I tried to find a game, there were no players listed, even for the original game maps.  I called support and apparently you can't find any players if you don't have all four of he DLC packs. You have to diable the DLC search in order to play any of them. Does anyone have a fix for this? I can undersand that there may not be any player using the new maps but why does that prevent you finon playing  in the maps you already have? In any case, I question if I am the only peson who bought DLC 4 in the world.THere should have been at lest one other person.
