[Client, Crash] Friend Groups

I tried to move a group up in my friends list and the client paused for a moment then did nothing. I tried again and the client crashed. (However, the crash has only happened once.)

Step-by-step:

Open friends list

Right click the bar of the group you want to move (in the list of: rename group, remove group, etc.)

Try to move the group up or down

The client will briefly pause then nothing will happen

No matter how many times you try the group remains in the same spot

[How frequently does it crash?] It only crashed the first time I tried, so far it just pauses for a few seconds and remains the same.
