It's kind of funny actually. I usually am zoomed out on the cloth map (because I've been playing large maps), and the statue for the enemy is still next to me after I killed them all. Now, if you zoom in, you'll see the guy die. He falls to the ground dead, but doesn't disappear. Then zoom out, statue still there, zoom in, and you can watch him fall to his death again! Hahah I have to admit, I did that probably a few times too many to be normal. This has happened with quite a few enemies, not any one in particular. I'll try to notice if there are any similarities next time.
Oh, by the time you hit next turn, they go away. I kind of like it. But I think I may get a bit too much enjoyment out of it. It distracts me from the game.
