Last Exception (again)

Hi Everbody!  Has anyone been getting this type of Last Exception?  I currently don't have mods installed and am still getting this error.  I even started a new save file thinking my other may be corrupt for some reason and still this....

I'll spare you all the other giberish in the notification but this keeps repeating every time "Unable to acquire ladder data for objID 497670746498728354.''  Where in the heck can I find out that object ID# from so I can get rid of it!!  It keeps messing with my dang game.  Been trying to figure this out for 2 days.

🙂Thanks for any insight!
