Basically, I started building a merchant. Unfortunately, I ran into that bug where the building goes in a different square to where you click. So I demolished the building, and built it in the spot where I actually wanted it. However, the building did not show up. I was on the cloth map zoom level at the time. So at this point, no merchant buildings were displaying.

I zoomed in to see what was going on, and it showed the merchant still on the first location that it had built, so I zoomed out. I then tried to demolish the building, in case the game somehow thought it was still there, but nothing happened, as if the initial demolish order had succeeded. Again, at this point, no merchant buildings were displaying on the cloth map.

Then I zoomed back it, and it showed the merchant building in the correct location (i.e. the second (correct) build order had succeeded), but the building was still not displaying on the cloth map.

Unfortunately, I can't say whether or not the building would have showed up at some later point (on the following turn, or after it had finished building) since I alt-tabbed to post this bug report, and the game crashed upon attempting to alt-tab back.
