I'm on 1.8.7a and when i hit Remove b-tag friends it won't work.
Pls fix it! 
I'm playing with italian version of it.

P.S.
Make an ElvUI skin :D

Did you delete your wtf folder or remove your saved variables file?

oQueue tracks who it added in your saved variables file. If you delete the file. It doesn't know who it added, and who to remove. 

I did when I installed 1.8.7
I removed all oqueue files and put the new ones.
But even now I can't remove "new" friends.
