I just posted a bug report about an inconsistency in the "BADGES" box of that I noticed on meta.stackoverflow.com (reverting to the previous "Newest" badge, after congratulating me on acquiring a new one in that box).
I posted the bug on meta.stackoverflow.com. I do assume that this affects other sites as well (but I have not noticed that far). But it cannot affect all sites, as not all sites have the new profile/acitvity layout (e.g. programmers.stackexchange.com doesn't).
According to the help-center bu. gs for all sites are welcome here on meta.stackexchange.com.
Not being sure that this affects other sites (I don't get a badges that often) and being sure if it does it does not affect all sites yet, should I have posted that bug on this site instead anyway?
