Are either of you having trouble with this? When I use quickstock it changes the url to the /qs, but still works without error, so I'm not sure if that is part of the issue.

This is due to the page lagging :(

You can try to refresh the page, but otherwise there is not much we can do as any sort of immediate fix.

Sorry for the confusion! That's the page that processes the items. Normally, it sends you to that page which processes moving the items, and then sends you back. So it's just lagging out on that middle step when it happens. I advise refreshing the page when this happens, and it may finish processing the rest of the items (and might give you errors for the items already processed, but those are safe to ignore) I hope this clears things up!
