I've been using this mod on my character who's married to Farkas, and had no problems, my other character is shaking up with Brynjolf and I can't get the kiss option to come up.
I thought i was doing something wrong, so tryed it on my married one. Took her to see Vilkas, when I clicked on him I got "00000014" as his number, after clicking on someone else, I finaly got the proper ID number. Tryed again with Vilkas and got the kiss option.
Tryed again with the one shaking up with Bryn, I can get the kiss option with someone else, just not with Bryn. I've tryed in the Thieves guild places, taken him to a couple of my houses, got him to unfollow, and still nothing.
I'm using the mod Brynjolf has time for you, would that be why I can't get the kiss option up?
Also, I got the "00000014" ID coming up on a few NPC's I clicked on.
PS, I've done the "GetRelationshipRank player" says he's 4, also done the "SetRelationshipRank player 4"
