I changed to force enemy dances to be animated off. This is because when an enemy dances in real animation, the unit icon for the danced target may change to incorrect.
The icon is buggy even when the saved data that can cause this problem is loaded into an unmodified rom and manipulated in the same way. So the cause is probably a vanilla bug, and the bug shows up because something was set to a value that could not be taken in an unmodified rom (though I can't say for sure since I haven't seen the code).
Saying that it was changed to fix a bug gives a very negative impression, but I think the enemy dancing animation should be turned off even if there was no bug. When the animation was on, it was very inconvenient as it was completely unclear to the players where and to whom dancers were dancing. I think this change has made it easier to understand what is happening during the enemy phase of the map where a dancer is.
