Colour Variations linked to photos disappeared

[MyCamino3D]

All of my products lost their variations. Anyone else has this issue?

Yes! This has been happening to me. I kept losing the variation photo links. I thought I had it all sorted out, but I just had someone order 2 out of 3 variations and suddenly 4 photos completely disappeared from the listing, not just the variation links.

I know this is a post from 6 months ago.  But the same thing started happening to me a couple of weeks back.  Listings I have had for years, that I have not edited, sizes and other variations have started disappearing.  I double checked on old invoices and the variations are definitely there.
