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

It's been a while since I updated the HD mod; I was using version 3.36.
Today, I installed 3.46, and I'm getting a message when I enter the tavern:

ResourseManager::GetBitmap816 could not find the "bitmap8" resource HPSPRAND4.pcx

The HD update isn't the problem; the issue is that in the latter case, the HD version isn't installed on a full, normal version of the game, but on a damaged, cut-down repack.

1 - I'm not rushing this; I'll do it when I have time.
2 - I don't know; maybe... or maybe not.
3 - I'm not rushing this; I'll do it for HD+ when I have time.
