[0.91.15] npcs don't cycle and stores don't generate items

[nuget102]

When you import a game in a city the recruitable npcs, or any for that matter, don't generate new ones. They use the ones from the previous save. Also, if you're in a shop and import that shop will have nothing to sell.

To reproduce: save in a shop in a city and don't reset squad positions.

P.S. posted this in modding by accident. Whoops.
