Hi Marlowe,
I'm sorry to hear you are getting it also, I have voted on your jira's, mine is back open now too.
First time it happened I put off going to help, as ya do... Hopin it would just go away or be a managable problem. But it became so severe I pulled listings off line and went to them, it happens only with my best selling set of stuff, has to do with auto fill. And now I after yesterday it is taking items out of VMM stockfolders and adding them.
Help were good last night. I went to them again as soon as it started happening and they responded with in the day, reopened the jira and I am going to keep a diary of issues and try and pin point it. SO they want to fix it.
I think gacha tradign is part of it, I do it in such a way that I don't like to let a listing go. I choose a collection that I can keep filled and trhere available long after the gacha round is done. So my listings become valuable to me, as the rankings i earn from longevity.
What scares me is how it just degenerated last time and already this time has gone from simply getting the error and being able to fix and relist with a fresh version folder to last night, while writing back to help, I opened VMM on SL to have a look and the error just started popping up with out any touching of any folder.
Is it still happening to you?
