Mod: Warhammer "Chaos Undivided" race

[Panpiper]

Hmm... Concerned that perhaps I had uploaded an incorrect built (it wouldn't be the first time), I downloaded the zip file from this thread. Using that file, I played a test game. I recruited all the various mages that Chaos is allowed, including getting the mage hero, and all of them had their magic path levels.

I expect what is happening is that you have more than one mod enabled and one of them is conflicting with the unit numbers for the mages. You are ordering the construction of what you think is a Chaos Sorcerer and the game is giving you some other unit that happens to have the same ID number in another mod. Try disabling the other mods and see what happens.
