PC Don't Log off on a bike...

[Alice]

I don't know if this has already been found, but whatever you do: don't log off whilst on a bike!

When you load back in the game has no idea where to put your character. So you get this weird bug where you're travelling through the world and slowly dying. You can't do anything until you die and respawn.

It can happen from logging in next to a vehicle too.  It's causes by vehicles rag dolling your character on game load - you're suddenly dead and 100km away.

Fixed in latest experimental.
