User Service Handler Exception

[jjtkalt]

Getting a frequent exception on the Robust console (versions 9037 and 9254). Been getting this for a long while. We have not found any in-world event that seems to trigger it. And we can't see any obvious impact from the user point of view, which is either comforting or extremely worrisome, depending on your point of view.

[USER SERVICE HANDLER]: Exception in method getmultiaccounts: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')

I have seen it on my Robust as well, in my instance it comes from opening a group or search for users.
