For what it's worth, I tried to install the same mod last night, and received a similar error, but with Viconia as the one blowing bad chunks. I also have TDD installed, along with (probably too) many others. One of those, apparently, was a multiromance mod, as both Jaheira and Viconia were having their way with me to no end.
Well, that's not true--it was to some end, as Viconia recently decided that, what with the demon attacks and all, things just weren't going to work out between us. Actually, that's one of the easier letdowns I've ever been given...but I digress.
I'd hoped the romance bugfix would finally stop my party's tendency to cha-cha across the screen (one-two-three, pause, one-two-three, pause, one-two-three, pause, cha-cha-cha), but sadly, now I may never know.
