After attempting to merge the replacer and patcher esps I get a particular navmesh error referring to: 0402AD3D which is a key: DLC2TGGloverKey "Glover's Guild Key" [KEYM:0402AD3D] Not sure if this is just a strange artifact of the merge or if there is an issue with the navmesh. Either way I cant merge any of the files with the common navmesh you are using. Not sure what is going on. Also, just trying to understand how things work, since that navmesh has the same formid in almost all your replacer/patches, and is also a vanilla formid, doesn't the last one win? It seems to vary a bit but that could just be it gets resorted for each esp. Just wondering how this works. It is preventing me also from merging the replacer version of immersive dg entrance with guarded border gates. And, generally speaking is it safe to merge some of your esps? Really need the slots having added most of the REGS mods.
