Bug Status/Moods Disappear on Refresh

I've been working on my postbit formatting and just noticed that when I go to a new thread, the status and moods disappear on the first auto refresh (5 seconds)

I'm sure I saw another post about this earlier as I was reading these forums but I can't find it now (I probably will as soon as I post LOL) is this a bug or normal behaviour?

A bit of both - USM doesn't support showpost.php, which is what the post refreshing uses.

So there's probably no fix for it then? No worries, it's not something I can't live with LOL
