I own a copy of the following..
Wings over Flanders Fields Phase 4
Addon Pack 1 (I think this is the fokker scourge)
Skins pack 1 (cant remember if this was paid or free)
I remember when I last logged in it was possible to buy the more recent content as upgrades, but now the store only seems to have Ultimate Edition.... do I really have to buy the whole game again? Or is there somewhere to pick up all the post phase 4 dlc?
