Hey bro, I added you because Im going to make an update to your esp so it will be far more compatible with other mods that also edit navmeshes in vanilla world space.

I noticed a few mistakes in the way you made the navmesh for 39 -1. When you deleted part of the vanilla nav, you split it into two parts and the vanilla nav became an island. The part you edited to go into the dungeon, a new nav. So when other mods that have navs that connect to it, the vanilla nav comes back ontop of your nav and both are present. It can cause ctds etc.

I will check other parts of skyrim this mod touches the navs on and make a comprehensive update to the navs which will inturn greatly increase its out of the box compatibility.

Lastly, the esp will be flagged with ESM using a script to detect quest related references to keep them persistent. You would hate your mod to be the last straw on the donkey's back on someone's "bloated" load order.

I hope you understand Im not trying to steal your mod or anything and the moment you update it I can take down any mirrors I have for the update.

Here is the ESP Update
