I added the most recent update into my server, start it up and it gave me a TypeLoadException for BasePlayer. I ended up having to pull the Assembly-CSHarp.dll file from last months update back into my Managed file to get the server to start running.

TypeLoadException: Invalid type BasePlayer for instance field Oxide.Game.Rust.Libraries.Covalence.RustPlayer:player

Sounds like some files didn't get properly updated, what host are you using?

I got it. Ended up saving my files and reinstalling everything
