I looked at your listings using one of my store accounts and I,m sure it showed over 400 listings. When I looked with this chameleon 54 account 30 seconds later I only saw 33 come up. I havnt got any answers, but it must be a worry for you.

edit - I just checked again with this account and 413 listings came up. very strange.

edit 2 - checked again, 69 listings this time.......

edit 3  -    31 listings that time.......
