It has happen again to me none of the DLCs shows that I own them in the store and I own WSR, HRO , BR204, Class 52 and Class 33. Anyone else got the same problem?
All worked fine for me, despite showing the price on the Store page, once I clicked on each Preserved Collection item, it said that I owned it, and was able to install them.
For Xbox users I suggest My games and apps Find TSW2 Mange game Manage game and add ons Select your hard drive Scroll and check add-ons appear Select add on Save changes Dlc will install.
