Me and my friends getting an instant crash in the beta when loading one of my friends avatar: "June optimised v5" by Junefree.

It’s 100% reproducible. All my other friends who are in the beta and have this avatar shown have crashed as well.

In the attached log file, I joined the lobby with everyone's avatars hidden and started showing them one by one - the second one was Junefree's and the game crashed.
