I'm assuming that this is related to the 504 errors and lag, but just in case it's not...

I am currently unable to sort any of the "unsorted" items in my vault. I am able to select the category they are supposed to go into, but nothing happens after that, even if I press the "move" button.

I was able to move stuff into categories, but it took a long time to give me the moved message.

When I tried to get back into the vault to make sure the items had actually been moved, I got 3 or 4 504s before I finally got back in.
