When I start a game and go to community mods and units, all the vehicles from the titan expension are yellow and i cant enable them. In the main menu it also offering me the titan expension pack, but I already have it. This bug appears since I linked my steam account with ubernet. When I try to buy the expension again, I can't because I already have it.
Post in this thread: https://forums.uberent.com/threads/linking-steam-to-playfab-can-lose-titans-ownership.71109/ and email support@uberent.com It's a common issue and should be resolved pretty quickly.
