This is sort of a two-in-one bug.
I was viewing the summary tab on Jarrod Dixon's profile, and all his accounts were listed as they should be under "Accounts." However, he should be a moderator on all of these sites, and only Area 51 had the moderator icon (♦) next to it:
I clicked "view more" to see the rest of his profiles, and they all have the icon next to them:
I went back to the summary tab to find that it had fixed itself:
That's the first bug. Any reason this happened?
EDIT: This happened again in Chrome. Looks like it happens periodically.
And on to my second bug. You'll notice that the ♦ icon skips a line for every single site. Given that this is happening to all of them, is this by design?
