Crash when certain players are in the lobby

[paltapica]

I was just in a lobby, not the host and all i know is that the player was marked as a known cheater, had no friend code and the attached is all i can give you, the game was freezing, accepted no input (so no log dump) and the BAU console was on a loop as shown in the attachment.
This was the second time i had joined that lobby with that player present and BAU crashed both times.

Hope this helps in some way.
