While browsing the network leaderboard, I noticed this:
It was not this bug resurfacing as it's the opposite: more hats than the count.
There is no trace for L'chaim and it must come from somewhere so my first assumption was that the user posted on December 5 and during winterbash that post was deleted. But this means hats are now revoked, which won't be very popular.
So, what does the hanukiah doing there and what happened to it?
While searching for the user to see if it maybe sorted itself out while I was typing I found this even weirder case: (and komorra is now gone)
For those looking to reproduce, just browse the pages starting at page 960 or so.
Note: this happens only for the Network Wide leaderboard, per-site leaderboards look fine.
