Erenya, after reading your comment that "the tortured souls romance a little naff to be honest" (see the link)
http://forums.gibberlings3.net/index.php?s...=4464&st=30I wonder why do you continue playing it? Just discard the whole mod and wait for Corthala Romantique being released as people at the correpsonding forums advised to you.
However, if you do wish to play TS, please report your problems as they should be reported: version of the mod installed, installation order, WeiDU.log if you play WeiDU version.
Furthermore, before you spent several weeks on finding what is wrong with your Valygar Romance and then discovering that you "wandered around for a couple of weeks more before setting sale" and this makes everyone happy including yourself, you would probably wish to read FAQ (by the way, written by Domi):
http://vlad.blackwyrmlair.net/faq.htmlwhere it is clearly stated that "the talk after which you can safely go to Underdark starts with Valygar saying *Do you miss Candlekeep*".
With respect to your last reported problem, please be more specific. I cannot guess what happens in your game. I need to know LT's variables before making any judgement. If "everything seems fine and I've just got him back after he was a vampire" is true then he should say something after ressurection (if I'm not mistaken).
Then in SoA, there are one or two more LTs. Last SoA talk for Valygar starts with "You know, everything shines about you...". Once again, there is some interval of 30-40 minutes of real game time before next LT is triggered. Also, some LTs are triggered by resting or being outdoors.
Good Luck!
