Suddenly this appears. If I expand the tiers, they're sorted in alphabetical order, so for BW2, it's LU-->NU-->OU-->OU Doubles-->Uber Doubles-->Ubers-->UU. In the other BW2 category, I find the tiers BW2 Uber Triples-->BW2 LC. Lots of weird stuff. Also user ghhglk is in his own nameless tier. This has happened a few times at completely random times in my experience. Edit: Should also note, this is only in Tohjo. Other channels are sorted as they should.
I wonder if this is caused by the removal of a tier such as Monocolor. If anyone was in that tier and hasn't logged on since, they would still be in the tier (in theory) but the server no longer has info on the tier and displays a blank tier.

I found something maybe related. I had it activate in reverse when i did "Sort by tiers" on another tab, then i closed that client and forgot all about it I reopened the tab to do something else and it created a hybrid sorting on the tab I had left open, where the new person joining the channel was sorted into the tiers, but the tab that stayed open wasn't sorted. I wasn't able to recreate this as it repopulates the side bar every time you change the sorting method, so there's something random causing it. I'll be trying to mess around with it for awhile cause I'm trying to find the cause of "tab" not working when sort by tiers.
