Fatal Error: MANAGED_EXCEPTION_CODE_V4 / 0x7fffb6a5804a - 6931268850 : crashes/d7a3e14b-27c8-4fa7-1c1c-f3a2503e1a40

All that happened was I pressed the close button on my editor window

What sort of tabs did you have open in s&box? How many scenes open, prefabs open, any popped out into their own window?

Yeah it's "crashing" for me every time I closed the editor. When I open it back up it looks like this: https://files.facepunch.com/ryleigh/1b1311b1/13_22-10-MassiveCreature.png

In the hierarchy, all the PlayerInfo and Bot stuff were created while the game was running and shouldn't exist. I deleted them and the editor closed without crashing a single time.

But then I opened a prefab and now they exist in the scene of all of my prefabs: https://files.facepunch.com/ryleigh/1b1311b1/13_22-16-ReasonableMarten.png
After I delete them the editor still crashes when I close it, and they re-appear in my prefabs scenes when I re-open.
