You on the latest oxide version?

I am currently renting a Rust server from Shockbyte, and as far as I'm aware they automatically update the game and oxide every time I Start or Restart the server.  I do not get any notices requiring any updates, and I have no reason to believe that the server isn't updated in those areas.  I also use Update Checker to know when any plugins are out of date, and all are currently updated.  I recently added 3 new plugins from CodeFling; Cooking, Convoy Reforged and XDQuest.  Shockbyte doesn't know what's causing it, and unloading those 3 new plugins hasn't stopped that new spam, so I'm completely lost and about to just delete everything and start over tbh.  I was hoping to find a solution to this problem asap to avoid that extreme action though.

Humm   i could contact shockbyte as there should be no issues loading that plugin.
Try and redowwnload imagelib maby ya got a bad download.
