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

I don't remember if this has been posted already or not. A save with a bug when purchasing troops. If you buy any number of any creatures in your home Castle, an extra unit appears. The error is consistently reproducible. It's a SoD save; I rarely play SoD in general, and it's specifically in that game where I've encountered this several times. I play WT+mod constantly and have never seen the bug once.
