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

Is Jebus from the HD set or not?

Yes, it's from the HD set.

Are you playing through GameRanger?

The game runs in Platinum, connects to SoD, all on one computer, without GameRanger or Hamachi.

Does this only happen with Jebus, or not?

I tried Jebus. On 8mm6, the Dungeon is needed...

There was another instance of desynchronization, which surprised me.

Damn. It's a mystery.

Now, yes. It's definitely a mystery. Yesterday, my settings were consistently messed up. (Created on 3.20, logged in with 3.19) but I don't think that's the issue. Today, it's not happening. I tried 3.20 on 3.20 and 3.20 on 2.98. Maybe it's something with the computer. Although, SevenSan also has settings issues.
