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

To be honest, I don't know how the spell reshuffle in Heroes of Might and Magic should work, as I don't play the original version. But after loading the save in both the original and the HD version, I got absolutely identical results. The spells changed, which means the reshuffle was working. Or am I missing something, and is it possible to specifically "configure" a particular spell?

Request: before reporting a bug in the HD version, make sure it's actually a bug in the HD version. It's not that difficult. You just need to repeat the action that causes the bug in both the HD and the original versions.

If the spell reshuffle is working correctly, spells should not repeat until all available spells have appeared. In particular, in Heroes of Might and Magic 2, Inferno has only 7 spells available in the original version (including Blindness), so a single reshuffle can give you all 7. In this save, Blindness doesn't appear even after several reshuffles.

Is it even possible to reliably determine that the bug is not related to the HD version by simply running the game in the "clean" original version? After all, the game as a whole, and this save in particular, were created in the original version with the HD patch.

I asked the author of the original version about this bug, but he hasn't responded yet. I don't expect to be able to reach the author of the HD patch
