During a large single-player battle, the AI moved a couple of its units and then just stopped, the message about how it's moving its units was still playing and I couldn't end turn; everything else worked fine, the first time it happened I went and spent five minutes tweaking my other cities' production queues and came back to find the battle unchanged. 

Last two autosaves, plus a save on the turn with the issue actively happening:

auto-save 1579.ctr auto-save 1578.ctr Erolki 1 - 1.ctr

Screenshots of the battle itself in the frozen state:

Log file just in case:

Player.log

I tried reloading the autosave for the turn and found it happened each time; my *guess* is that either the reinforcement is somehow glitched or the pathing's confused and trying to use the harbour even though my units have the land tiles beside it filled up so they can't disembark there. As a test, I left a tile open to let them land a unit through the harbour and while they did so, afterwards it just stopped again:

I might or might not go back some more and see if putting my units in different places escapes the bug, but I've tried a number of times now and am skeptical any straightforward changes will solve the issue (other than just surrendering or otherwise avoiding the battle entirely, of course). Thank you for your time.
