City marketplaces list items multiple times

[Pilgrim]

When I'm looking at the luxuries in a city's marketplace, sometimes the "next 20" button gives inconsistent results, like items being listed in two different places, and other items not listed at all.

I discovered this when I was cutting and pasting entire marketplaces into a spreadsheet and then sorting by item name. It doesn't happen all the time. There's a usual order in which the luxuries are listed (I'm only tracking luxuries), and when I see that order, I know I'm ok. But when the luxuries come up in a different order, then I double-check and sure enough, there are duplicates and missing items.

It happens intermittently. I'll try to take notes the next time it happens.

I'm not a database expert, but I suspect that instead of getting a whole search done and just displaying the results in pages, that each page is a new search and the order of search or the underlying index changes between "next 20" pages.
