I played the game at a stretch for like 4 hours, sometimes idle but still in game menus or lobby and after the final match, had 2 cases as loot. But when I tried to open them, the first time it just sat there saying ‘Please wait’ indefinitely, then I cancelled that and tried again, this time I got the following Error.
Then I restarted the game, and I had no cases at all.
(Also, when I got that above message, it wouldn’t load any of my loadouts cards either)
