Hero Splitting

Not long ago, there was a bug (the save file is gone). I attacked a Fairy with a scout and a small army and lost the battle :D. And in the next attack on the Fairy, the battle wasn't with them, but with my hero who lost under a neutral flag, but as soon as his army's turn came, the game crashed :confused:. I've encountered this duplication issue many times, both when playing against the computer (when you and the computer have the same hero) and when playing online in a town; the hero duplicated, and I had to dismiss the main hero :(. I even encountered a duplication of a Castle, and even when they turned gray. P.S. Take a look at the blue player's save file; is it a bug or...?
