Lots are disappearing in the base game cities.

Good day.

When rebuilding lots from expansions in Willow Creek, the lots disappear. They remain on the city map, but if you go into the lot, it’s empty — only the land value is preserved, with no building. Moving the lot to another place doesn’t help; the only solution is to roll back to a previous save.

The lot type used for rebuilding that breaks the save can be any: rental housing, custom lot, or residential house.

The bug doesn’t appear immediately. After rebuilding expansion lots, I go to a lot in Willow Creek, and if a neighbouring lot looks like it hasn’t been rebuilt, the game is broken — and things will get worse from there.

I’ve been struggling with this issue for several months. I hope you can help me find a solution.
