Yeah, my stack of PM notices is not going away right now.

On the up-side if you want to re-sync your PM count, just load your folders. Of course, I'm not really sure why people didn't want PM counts that never changed.

Oh, I'm keeping my -9. Can I delete my inbox without it refreshing my sent folder?

Mine still go away, so I have no idea what is going on.

Recode the whole thing?

I added a functional fix: if you see the mismatch warning dialog and things did NOT work right, you can reload the page with the other setting by hitting the "Retry" button.

Expected behavior: notices should now disappear automatically, but you will need to switch to v5 data mode to resync your inbox count.

The UI sucks, but it's all I could do to provide functionality in ~10m of coding.

Devourer has talked about doing that. It will just take a long while, and a lot of motivation. for now, the hotfixes will have to do.
