Server Error

[NateDaBeast]

Whenever I join my server I get this error listed in the image I listed below. Once I press continue it proceeds me into the game but still I would like to get rid of the error.

The following spoiler is a log I found in the RPT log that I think relate to the issue

Spoiler: Code
