Just thought I'd post my little fix for Rise of House Telvanni. there's a small bug, where if RoHT is used with Wakim's Game Improvements, NPC's who shouldn't be able to, can now cast Alighiere's Blood Thirst. This is far too powerful for the low end NPCs, and this mod fixes that. Just a simple fix for those who don't know how.
