Wow, amazing mod. Never realized this type of thing existed for Heroes III. After looking over their forum though, I wanted to point out that Celestial Heavens
has three additional official updates for WoG. It's their new official page too.
On their page, it doesn't mention which order to do the updates. The patches require that first you do the script update, then you manually replace the two bug fix files to complete it. It's not 3.59, but it does fix a few things.
