Description: When capturing a region controlled by another faction where a Wonder they claimed is being built, completing the wonder causes the game to hang with a "Turn Pending" in the status of the turn button.


In my example game an AI player playing as the Greeks had claimed the Gardens of Babylon. They had begun construction of the Wonder in a region that they surrendered to me via a Demand over the mistreatment of my people (Cultural Conversion demand). Once I gained control of the region the Wonder was still in the same tile and under construction. It could be selected as a project for any of my cities, like any other wonder. On the turn where the Wonder completed when ending the turn the game hung with the turn progress button showing "Turn Pending."


I reloaded the save and repeated the same steps from the previous attempt with the same results: hung with "Turn Pending." Reloaded again, switched all construction to other projects and did not complete the Wonder. This allowed the turns to progress, and remained progressing as long as the Wonder was not completed. On a later turn I switched production back to the Wonder as a test and got stuck with "Turn Pending,"


Attachments: Attached is my most recent manual save and last two autosaves. The Wonder is still present and will complete in 1 turn with any city production set on it. I have also attached all of the Diagnostics files from my play time today when I encountered the issue.

Steps to Reproduce: Begin construction of a Wonder. Transfer ownership of the region containing the wonder to another player. The new player completes construction of the Wonder. Bug is encountered.


Expected  Behavior: Unsure of intent within the game design. Either the Wonder under construction should be removed so a player who has not claimed it cannot build it; or the construction should be completed by the new tile owner without causing this softlock.
