Yep, what I am talking about is of course the misplaced barrels that blocks the door into the Alchemy room in Breezehome between Skyrim without HF and with HF installed. For the first time, I now use USLEEP and below is my loadorder.
Active Mod Files:
All mods have been cleaned with the latest TES5Edit, unless there is newer version available, and I also follow alt3rn1ty's guide for manual cleaning of the Skyrim master files.
These mods are the only two mods (plus a patch for OCS, if it's installed) that change a few things in Breezehome, but I doubt that since these mods didn't exist at that time when I posted this thread 3 years ago (I didn't want to necro that thread, but feel free to merge this thread with the older thread).
Breezehome Firepit Removed+OCS - BFR Patch
Breezehome Loft Crafting (I don't think this mod can cause the issue shown in the picture)
I also read some old posts and I think this post is something that I applies for Breezehome. A bug fix or bug fixes that cannot fix a bug, which I think is a bug for a mistake in design that Bethesda did for Breezehome in HF.
So how to fix the misplaced objects, well the way I see it is to re-create the Breezehome cell from scratch or let Lydia *own* Breezehome since this make sense.
This mod switches the location between Breezehome and Carlotta's house in Whiterun and I think a similar mod can fix the main issue(s) e.g misplaced objects, *broken* navmesh in Breezehome.
