This mod turned into a "must have" to me, great work, but I've had some issues with the tie system:
You see, I downloaded Underground Bathhouse, so I thought "What if I build a slave prison with tied up girls?", in the beggining it went well, I permanently tied up few bandits and everything was working fine, but then I tied up Karita (http://elderscrolls.wikia.com/wiki/Karita_(Pilgrim)), it's written in the wiki that she is permanently erased from the map once the player reaches High Hrothgar, and she really did, after that I simply used the clean tool and no problems happened, but I realised that Karita wasent the only type of NPC that would eventually disappear, the same happened with Cultists (Dragonborn DLC), Thalmor Soldiers, Necromancer, Witches, Orcs (Random event), all of them, even with "permanent tie", will eventually disappear (Sometimes when I'm carrying them on my back, the moment I try to release they just don't appear), the strange thing is that I can still see them in the registry tool. The only exception are bandits.
I dont know if that happens just to me, but if it dont, is there a way to fix it? Thank you for your attention to anyone that answer this. And sorry for Bad English
