Looks like it is RustEdit that is the cause of the error spam.
Tested on a 100% clean install (no errors), Clean install with just UMOD (no other plugins, no errors), UMOD + RustIO (no errors).
But when I had it with UMOD and RustEdit, it spammed the errors like mad.
So looks like it is RustEdit that needs an update to stop the error spam mentioned.
Ahh perfect, I'll keep an eye out for an update. Thank you for letting me know I can rest easy now.
