Yeah, this version definitely shouldn't work. According to my limited and amateur testing the original,
here, intended for for vanilla FFH works fine though, with a few quirks.
1. Because Desert Rose is a resource Magister added there won't be any. I believe, but am not certain, that all other non-mana missing resources are hell-terrain or event resources that should appear as normal.
2. The unique features he added will also be missing including all of the bones from the other dragons.
3. All of the mana nodes will be raw except for those provided by unique features, which is a problem for two reasons.
a. This is clearly not how MagisterCultuum intended the mod to be played, since unlike other modmods the randomized nodes are not optional in game set up. So if you're looking for the full intended experience you aren't getting it.
b. More importantly, this point combined with point 2 means that there will be NO sources of creation mana on the map, and as creation nodes can't be built on raw mana, there will be no creation mana in the game except what comes from palaces and shrines.
Of course, all of these problems can be fixed either by hand, or I believe, by setting the randomize resources and randomize unique features option in the map file (although that will mean you aren't getting the intended experience of the map, which presumably had it's resources painstakingly placed and balanced).
