We're told to ignore them, to click on Yes To All but what exactly do these error messages mean? I had my share prior to modding and now I seem to have created more of them when loading my plug-in and the cell I'm working on.

So, here I've listed all the errors in an abridge form, using "blah blah" to shorten them etc. An explanation on what these mean, the ones to ignore and the ones that really ought to be looked at would be nice. Oh and how to fix them too, like the Navmesh errors.

loading the plug-in:

1. MASTERFILE: Unique ActorBase 'HousecarlWindhelm' (000A2C90) has more than one reference in the world. Data access when unloaded may not work correctly
2. MASTERFILE: NavmeshInfo 00028e37 has no parent space, ignoring
3. MASTERFILE: Errors were encountered during InitItem for reference (x8 - various Base objects in different cells)
4. PATHFINDING: Navmesh 020093d8 Cell 'WindhelNewHjerim' (x11 - various Triangle, Edge not linked, or have opposite normals but are not linked)
5. PATHFINDING: "------------------------------------------------------------" (x3 - as above but are linked and their vertices do not match)
6. PATHFINDING: "------------------------------------------------------------" (x2 - Triangle ### has no link to Triangle ##, but Triangle ## doesn't have the matching link)

loading the cell being modified:

7. TEXTURES: Texture Set missing texture textures\clutter\charcoal\Soap01.dds (x2 - to do with my new soap mesh copied from coal, texture works just fine though)
8. TEXTURES: Base data\Meshes\Soap.nif: Coal01:0 is missing a diffuse map
9. TEXTURES: "-------------------------------------------------------------------" normal map
10. TEXTURES: WallMountedGoat01 : Goat01 Posed is missing a back lighting map
11. HAVOK: File contains a phantom with mesh shape collision. Please remove shape of convert to primitive (x3 - doesn't specify what they are)
12. ANIMATION: Project DeafultFemale's event name IdleFreaSorrowLoopEnter linked with a different capitalization already (x2)
13. MODELS: 3D for Ref 'blah blah object' (ref number here) does not support external emittance but has explicit emittance data (x4 - various statics, mostly walls)
14. TEXTURES: PlayerHouseMannequin..blah blah blah, is missing a specular map (x2)

Cell then loads. Despite all these errors the cell functions just fine in the game, although I haven't tested followers AI paths through my modified Hjerim house.

Some of those are good to note, but for the most part, while working on my own worldspace, I became quickly annoyed.
So I did this.

In SkyrimEditor.ini:

bBlockMessageBoxes=1

You saint! I've been wondering about this myself for awhile but I was too scared to ask. I feared that I would be strongly discouraged to hide the warnings.
