ok what i done now:Wulf
Form your log, you are using an older Oxide build. You'd need to update to the latest.
1) delete dir "RustDedicated_Data"
2) then i run validate (RustDedicated_Data is now original without oxide)
3) i download oxide again from umod website
4) extract RustDedicated_Data and rewrite all existing files
5) start server
and problem is still here.
