A1: 'A common cause' Hulrun vs Ramien?

Something weird happened today: Ramien refused to join my forces. This has never happened to me after using the two [Angel path] responses to talk Hulrun out of attacking the Desnans.

Instead, Ramien said something along the lines of 'Thanks for saving my life, but I fear my presence at the inn would just incite Hulrun again.' -- and left.

The only option I now have is to talk to Hulrun again and ask him to join, which he does.

It's not that this is a major issue -- I'm just baffled this happened after I always sailed through with the Desnans almost automatically and only got Hulrun once when I was playing LE and killed Ramien myself. Could it be that Ramien senses my CE alignment this time around? Are there additional triggers that decide whether the Desnans join or not? Was there a change that flew in under the radar with the latest patch?

I can only think of two factors I did differently this time around: Alignment (CE) and I killed the crusaders threatening Ember on the spot instead of talking them out of it. Everything else, to the best of my knowledge, is the same as my other playthroughs that got me the Desnans.
