Can’t seem to unfriend someone on my friends list. This has been a problem for weeks & months but now there too many people on the friends list that I get spammed with online pop ups.

 

Typing “/friend (username)” attempts to add that particular friend rather than removing them.

 

I’ve tried deleting and reinstalling to no avail and also added them and removing straight away afterwards which still wouldn’t remove them.

 

Any other suggestions have already been attempted so would it be possible to reset my friends list completely?

I got the same issue here.

You could try messing with the game files and seeing if the friends list is stored locally but I doubt that's the case. /ignore is the only way I think.

just do the /friend name again and relog.. its a visual bug good luck !
