I can’t buy any of the new premium cosmetics. Pressing the ‘acquire’ button does nothing. I’ve got the steam overlay enabled, so is there anything else I can try?
This is odd, I recall a while back there was an issue where sometimes the redirection to the purchase page would be delayed, sometimes popping up 10 minutes later whilst in a map! Have you experienced anything like that?
