HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Unusual behavior of my heroes during the opponent's turn. They disappear and vanish from the map. Everything returns to normal during my turn. It's not critical, but it's unpleasant and I don't understand why it happens. I used to play with the bug fix option disabled, and now I'm playing with it enabled, and that's when these issues started. _________ By the way, it seems like this happens if you right-click on them... but not all of them disappear.
