No one can buy from my shop and I can't retrieve items "steam session of the bot needs renewal, please wait"
Edit (2 hours later...): K, this is really dumb. Why is this happening? Missed some really crucial sales because of this...
I was asleep when all of this happen. I think Steam Community shut down about 7 hours ago for a couple of hours. So every bots lost its Steam sessions and all tasks are stuck. But the site's auto recovery system works really well. All bots successfully reconnects and got all queued tasks carried out. After I wake up everything is already back in order and nothing has to be fixed manually.
