I just looked mine up in the browser and in-game. Varied results, but neither way seemed to bring up full results (if any), aside from my most recent uploads. Then I tried on the in-game filter selecting 'most popular', then that brought up tons of stuff that was not showing &/or populating. Then I looked at the bug report that Crinrict linked to and it looks like they did not get results with 'most popular' selected, but I up-voted it anyway, and will add my information about the odd gallery results. So, experimenting with settings seemed to help for me, but adding search terms seemed to help for them. For both of us apparently the search and results/loading is behaving in a buggy way. Up-side to this may be that there is not an issue with your lots being gone, perhaps the issue is just that the gallery is currently being temperamental (&/or buggy) about loading them properly?
Edit: Actually, when I did the 'most popular' search I did select the 'user ID' and had my name in the box, so that may also be a similarity.
Thanks for your reply! That's what it is. Selecting "Most Popular" made the rest of my lots show up. I'm glad it's a filter issue and my lots are still there.
