Thank you.  I've gone through and moved a bunch of those N64 sales to the correct items or deleted them.  I also added some backend code to automatically move those N64 sales for particular colors into the correct item, even if the seller listed the item incorrectly.  I also manually added some additional sales.  

Can you give me some example sales that you reported but they were not removed?  I want to look into those and see why they were not removed and reviewed by admin.  Thank you

Can you elaborate a bit more?  I don't quite understand.  What variants?  And where do you want me to put them?

I've fixed as many of these as I could identify.

That will be in the menu with the next server update.

All that I've found have been moved.  The site won't show the update for about 12 hours.
