I know nothing about it but if that's the source of the problem then we'll have to burn a few dresses.
I agree with that sentiment. A lot of items could go, but there's always that -ONE- person that loomed it and will be upset.
I say just refund them whatever looms they lose, and be done with it. Gameplay smoothness > amount of items.
(All this is just hypothetical, as this being the cause of the problem didn't come from the most reliable source)
