Badge strange behavior

[Alicemirror]

Hi to all,

I see that there are some badges (like Developer summit 211 and Qt Ambassador) that are static: when activated on a user never changes. There are badges like groupie, thread master etc that are dynamic: as the user change (i.e. subscribe to new groups) the level grow in the Groupie badge. Then in these days I see that some badge i.e. at the moment my Threadmaster badge that appear and disappear. Now it is now on. Is there a reason?

Yes, but "Thread master" is even more dynamic, since it means that you started at least X threads in the last Y days (therefore, it can suddenly disappear at the Y+1 day)...

Wow... It's clear. Just to be sure that it is not a problem...
