These tall buildings are really neat, but I'm not liking putting short buildings behind tall ones because I want to see them. To that end, I'm trying to swap the location of two houses, putting a shorter one in front of a taller one. I don't want to lose the population, so I'm also dropping some extra housing to take these poor huwans while I rework their homes.
In this case, there is a Orchid summer house behind an Ember I-forget-the-name tall 40-occupancy building.
I place two spring houses, assign them to Orchid, then try to remove the summer house. The game hangs.
If I place zero or one Orchid spring houses, things seem fine, though I lose people.
A third spring house did not help either.

It is at the start of the scenario, before any spring houses are placed for the move.
