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

In version 3.19, when gaining experience (from a chest or any other source), if the turn time runs out, it becomes impossible to choose which stat to increase, and the game does it for you! This is ridiculous. Also, if you select "Jebus" in the settings of version 3.19, set "Hard" difficulty without underground, and then switch to "Castles," the settings mode reverts to a map with underground!
