SFO: Grimhammer III - UPDATE IN PROGRESS
Cannot Awaken Tribes as Belakor
I apologize if I just missed this in the change log; I checked both the last two changelogs but may have missed it.

But I'm having a problem as Belakor where I'm invading Norsca but can't seem to awaken any tribes as vassals despite taking places that show which tribe can be awakened there. I can see the option of "gift to vassal" after battle but the option is grayed out and can't be clicked on.

Am I just missing something silly? To make sure, I started the game without any mods and went in again as Belakor and have the option to awaken the different tribes on capture no problem.

The only thing I can really consider is that when I took the formal capital of the Nargfalgings (sp?) the Doom Keep, the associated tribe was already confederated by Wulfrik and the rest was held by the Slaaneshi WoC faction. I thought it would let me reform the tribe but maybe I'm completely wrong.

Anybody able to help out?
