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

At the request of Medium. A serious bug has been discovered. In game 8mm6a, WT+HD, the bug does not occur on a clean WT, nor in Hotsite; an online connection is required. The essence of the bug: when a red hero attacks a blue hero standing in a Dungeon, the battle is displayed on the Dungeon landscape on the red hero's screen, but on the blue hero's screen, the same battle takes place on grass with the corresponding landscape bonuses. Two save files are attached. In both, you need to pass the turn from blue to red and attack Ash in the first case, and Brissa in the second.
