Not sure if this is something you're aware of, but I've had instant crash to desktop if someone hits me too hard.
I was on a custom track server, I crashed and reset. I noticed someone coming towards me so I didn't move, thinking they would avoid me which they didn't.
Must have hit me at about 30mph at least, and instant crash for at least me.
Thank you for the report.
Did the other client have a high ping?
No it was a white name that approached.
