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

I'm currently reading the description for version 3.0. It says that the bug with the refugee camp has been fixed. Does this mean that if one person has HD 3.0 and the opponent has SoD, one will have a black dragon in the camp while the other has a pikeman? Or does the bug fix only work when versions are identical?
