Simply unsubscribing/unselecting a DLC will not solve the problem, you have to delete the content permanently. On the other hand if the DLC is free of charge, mismatch will not be overcome by a simple download from the server. When we're talking about DLCs that have a price tag on them, download obviously does not initiate. I'm no expert but I think that when ever two players are "checked" in the online/skirmish room, steam tries to load the exact same DLCs that other player has to the player lacking them. At this point it was obvious that it was because of the skins, decals and faceplates.īe noted that any custom skin can make the mismatch between players, CoH2 interprets skin as a mod? When you use common skins, faceplates and so, no problems such as mentioned before should occur. Now it tried to load something over and over again. After this the game gave the same error "Player has selected a mod that one or more party memebers have not installed" but with different results. My brother finally purchased "British Forces" and "Ardennes Assault" because we got so tired of this BS.

This was indeed a DLC issue as I expected. After almost three long weeks I've been able to find solution.
