First post on here, hope it's helpful. Had the same issue with stairs clipping through the fireplace and stuff. Just spent an hour or so tampering with SSEEdit and got it to work. Here is something of a guide for those like me who haven't really used it: 1. Open up MO2, run SSEEdit 2. When the "module Selection" window pops up, right-click and choose "select none", then either scroll or type Lux in the filter bar 3. Left click the checkbox for Lux.esp, it's the only one that matters for this, then click OK 4. When the process completes, navigate to the left pane and click the little plus next to Lux.esp and then do the same for the subheading "Cell" 5. It should give a list like Block 0, Block 1, etc. through Block 9, inside of each should be several Sub-Blocks 6. Click through them until you see something akin to "BYOHHouse1" and select it (I Believe the main house is in Block 8 and the cellar is in Block 4, can't remember what sub-blocks as I am writing this retroactively) 7. If you have left-clicked on the correct one, the right pane should show that it is conflicting with "LKVM Main House.esp" or "LKVM Cellar and Exterior.esp" depending on which one you are after (in the case of clipping stairs, it is main house) 8. Once you have selected the correct cell, simply right click on it in the left pane and select the "remove" option. 9. A window will pop up asking if you are sure. when the timer finishes, select yes. 10. When you are satisfied, close down SSEEdit. It should give you a prompt asking if you would like to save your changes, select yes. 11. Boot up Skyrim again and profit. If you get it wrong, don't worry. Just go back to nexus and redownload lux, everything will be restored and can be looked over again the same way. When I did this, I loaded back into my current save (which was even inside the house) and everything was normal. If that doesn't fix it, try re-instancing into the house or reloading a save from before the house was built. Make sure you also follow the directions on the mod page description. Hopefully this guide is specific enough for those with less computer know-how than myself. If not, I will try to make edits accordingly.
