@ss_rakesh Hello. I downloaded all the "faf_coop_maps" zip (because the sub folders doesn't seem to have an interface for downloading), unzipped, then i picked the "FAF_Coop_Operation_Overlord_Surth_Velsok" and copied it in the folders path mentioned after i have created all the empty folders (because they doesn't exist after C:\ProgramData\FAForever) then i also created another same data folder named FAF_Coop_Operation_Overlord_Surth_Velsok.v0000.
But the coop mission doesn't appear in game map list.
Then i put them in the maps folder that the FAF client open with the top left command, that make them appear two times with same map title, but sadly both have a visual glitch that flickers/flashing the light over all the map(i suspect that is related with the splendid lava effects). Maybe the dev notice the bug and cancel the files from client downloading but can't remove the map from the list. Thank you anyway for helping.
