Solved Player Disconnecting with error: Argument cannot be NULL

Full Error Message:

Code:

REMOVED:52084/REMOVED/REMOVED disconnecting: ArgumentNullException: Argument cannot be null.
Parameter name: source
System.Linq.Check.SourceAndPredicate (System.Object source, System.Object predicate)
System.Linq.Enumerable.FirstOrDefault[Skinnable] (IEnumerable`1 source, System.Func`2 predicate)
Skinnable.Find (System.String itemType)
Rust.Workshop.Skin+<FromFolder>d__5.MoveNext ()
UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress)Version: 21894

Any idea what is causing this? I don't think it's my server as only one person is having this issue, but would be nice to try and help them fix it.

Thanks!
[DOUBLEPOST=1501563078][/DOUBLEPOST]This issue was resolved. The user restarted their machine and they were able to load in after. most likely bad bits in RAM causing the issue.

Marking as SOLVED!
