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

Ivor, maybe you could just fix the bugs properly. The description of a critical bug has been in the WT-innovations thread for six months now.

What's stopping you if it's that simple? Especially if this bug with artifacts left behind bothers you so much – why don't you fix it? I tried to figure it out – but haven't been able to yet. And there are more interesting things for me to do.
The fact that I posted the save is good; I downloaded it, and I might try to figure it out later. Or maybe someone else will fix it. As far as I understand, Baratorch doesn't plan to fix Wog-related bugs.
