Game crash upon rejoining server - "Camera entity from checkpoint does not exists!"
My friend and I have been playing a survival server recently (me hosting, him joining) and have run into this bug twice now.
Upon him attempting to rejoin my server - whether from invite/join from server list/etc - his game will start to load in, but then freeze (during the "Streaming" part of loading), and then the game will crash to desktop. SpaceEngineers.log shows this line of note towards the end:
2020-01-06 15:11:06.195 - Thread: 1 -> ERROR: Camera entity from checkpoint does not exists!
He only gets this problem trying to join this specific server. I spun up a different server and he was able to join just fine.
What we've tried to get around it:
When this happened for the first time yesterday, we eventually "fixed" it after deleting his shader caches, purging all references to him or his steam ID we could find in Sandbox.sbc (done manually as SEToolbox is apparently broken ATM), and kicking him from the faction. After all this he was finally able to rejoin. Today, it happened again - notably, it started again when he tried to rejoin after his connection temporarily dropped and he disconnected - and after doing the same steps we did yesterday, he is still not able to join. Edit: Though he can get past the faction selection screen, it crashes on the spawn point select screen.
His SpaceEngineers.log and VRageRender-DirectX11.log are both attached. If it helps, I can provide the save file as well (though it will be the version after we attempted to purge him).
In the meantime, if anyone has a suggestion on how to better make a server "forget" about a player, it would be appreciated, as right now we currently cannot play together on our survival world.
