Hello,
It might not be much helpful but I managed to figure out WHEN this bug occurs. I consider it as the most important bug of the latest patch and, unfortunately, I come up with bad news...
This bug triggers EACH AND EVERY time you choose to build a district or a wonder and decide the location of its construction.
,
More information on this issue:
1. The bug has nothing to do with tech / civic choosing or queuing
2. The bug does NOT trigger when choosing to build buildings (that don't require to be taken to the screen where you choose where to build them), units or projects
3. Saving the game and reloading CANCELS the bug until you decide to build another district or wonder
4. The bug has nothing to do with city management, tile purchasing, trading, leaders, wonder replays or any other action
5. I tried to build something else and change the production to district / wonder and, unfortunately, the bug triggered
I tried to edit the txt and other files which are related to city screen but was of no use.
However I thought it might be useful to share with you at least when this happens. Theoretically if after each district / wonder choice you save/reload the game (F5/F6) you are not going to miss any of the pop-up dialogues.
The problem is that, assuming how many times someone chooses to construct a district or wonder, it's really tiring.
I hope that a solution comes up soon
