New RPG map for Heroes 3.

Talarasha, could you provide more details: which version of "Heroes 3" do you have, what patches are installed, which WoG version, and which Russian language pack?

Heroes 3 version 4.00 corresponds to the Platinum Edition from Buka. No patches are installed, except for those that are personally important to me – replacing portraits and music.
I haven't tested it in WoG; I don't feel like downloading it. However, I'm confident that it will work fine there as well. The problem is 95% not related to the map itself, which can be confirmed by the fact that only the first version of the map works for you. Although the last one is also marked with SoD.
Conclusion? The conclusion is simple: since the problem is observed only by you, common sense suggests that you should investigate in that direction.
