disturbances

Hi I just logged back from a few years of break and I find my marketplace inventory having empty folders - without me receiving any money. The folders are still there like some placeholders. These were no copy KittyCats cats and I'm worried they are lost? They don't show in my pedigree either which is weird. Honestly, I asked 10k for one and I'd RECOGNIZE that amount of money if I ever received it. I'm not talking about 20Lindens. What can I do? I could only redeem my items if I had the ID number but as I said the pedigree does not show them anymore either. Is it possible that they were glitched out from my marketplace and pedigree without leaving any trace behind?
