I've experienced an issue several times now where a city will not be captured after a victory in battle.  This appears to happen any time the defending city has reinforcements participate in the battle.  I will fight the battle, kill all enemy units, including reinforcements to get the battle victory screen. However, I will not capture the city. This is especially annoying when a neighboring city is close enough to reinforce with it's militia units.

Version: 1.5.7 S3 (64-bit)  All DLCs installed, Tempest not enabled.

I've included this zip file which includes screen shots depicting the issue, the save file for the turn in which I'm experiencing the issue, and the Registry.xml file. Please let me know if there is other information I should provide.
