[CLIENT] Client Crashing When Moving Friends Into Groups

Just as the title suggests, every time I try to move a friend into a folder, whether it's a new group folder or one that I've been using for a long time. The client instantly stops responding and crashes without completing the movement. I have tried it several times and can recreate the bug at will.

UPDATE: Bug died down for a period of time and then resumed itself. This time from adding friends, removing friends, and deleting friend group folders.
