Lydia not dismissing

[thatperson14]

So I decided to download Hearthfire today and so I made a house, brought Lydia there afterwards and made her my Steward. Problem was that after I had done so, she would continue to follow me everywhere, through every cave etc. I couldn't get rid of her. Serana is always in tow with me and I am able to dismiss her properly, but Lydia just don't leave. I have tried set playerfollowercount to 0, it didn't work. It also didn't send Serana back, but I'm not sure if that's normal or not. I tried killing Lydia only to find that she was marked as essential. I set her to mortal, killed her and resurrected her and she continued to follow me. ResetAI didn't work, disabling Hearthfire didn't work either. I would disable Hearthfire, load up an early save point and recruit Lydia and test all commands and anything I could do to get her to leave after asking her to follow me, but nothing worked. As for follower mods, I have only tried out UFO today to see if it would fix my problem, and I also downloaded a mod to trade and swap default armour on companions, it doesn't seem to be causing the problem as I disabled it and the issue persists.

 

Is it possible that fragments from old mods could be causing my issues? I searched for this problem for quite some time and came up with no solution, that was said to be a potential cause. Any help is greatly appreciated.
