She is not in Spellhold and/or she is duplicated and/or you meet low-level Imoen (different from yours) in Spellhold because some of the mods rewrites my already modified in NeJ2 script CUT01.bcs. Occasionally I've spotted this problem in BGT, which also modifies CUT01.bcs, and then WeiDU cannot find the matching block and hence ignores it.
then is there anything I can do about it except wait to ToB and summon her in pocketplane?
