I was playtesting my project and Snow joined my game to see what I had made. He was going to place an explosive barrel device which seemed to have crashed my game simultaneously.

Thank you for the report, the team is looking into this.
We were able to confirm this crash and suspect that it might have been some network serialization errors that caused this. Some fixes went in for an upcoming version so hopefully it will be fixed soon.
Thanks.
