Multiromancing is generally not supported by NPC/romance mod makers, so it's best to mention that you had multiromance first
so nobody would help you- it's probably what caused all the issues in your game.
I thought I mentioned it in the first post, I guess I only mentioned the accelerator and banter packs, my bad.
On this topic though, I really don't understand why multiromance is not standard. I just want to see all the content and play all the quests. Just like multstrongholds, I don't understand why that wouldn't be the default for modmakers. Just don't mess with other NPCs romance variables.
