I have spoken with the frontier support and well, they have told me that for buying the DLC on steam if steam crashes, I can't play Odyssey, neither in the frontier launcher nor in another house, let's buy the DLC on steam to control the hours of play and I find that surprise, that either you buy it in frontier or you forget to play it if it goes to hell with steam, it has told me that if we want to change it we should complain
