So I used the sort button while I had my mailbox open, and my inventory was deleted. I created a ticket explaining the situation and received a response saying to update the ticket giving specific items of what was deleted. I know a few items, but my inventory is huge, so I have no idea how they expect me to know all of it. They also smoothly closed the ticket, making it impossible to update.
I'm sad because I'm an original subscriber, and feel like I'm not going to get my inventory back.
