I preordered the shadowkeep digital deluxe edition, and so did my friend. At the launch, when it came to steam, we both had 3000 silver, so i think that would be the normal cause. Later that day, the servers went offline for a while, as we all know. And the next time i played the game, my silver was gone. My friend's isn't gone. If i click on the silver symbol in the inventory or if i would try to buy silver, an error occures which says "Unable to contact marketplace servers. New Silver purchases will update when you next sign in." But i've already logged out and in again multiiple times, even with restarting steam when i was logged out didn't do anything.
