Oh come on! Blaming struggling modders for Bethesda not fixing their problems is outrageous to say the least.
And people jump down my throat for selectively quoting out of context?
Anyway, as SWG just said, that wasn't directed at "struggling modders" so much as it's being directed at those who are insisting on feeding them bad advice.
Look at it this way. If you make a mod with a navmesh in it right now and you DON'T follow that bad advice, who gets the blame? You can point fingers at Bethesda all day long but your comment threads will fill up with ignorant people who will insists they can prove YOU broken it.
If you DO follow the bad advice, and everyone else does too, then what you end up with is a whole mess of mods out there where everyone ships with 2 files minimum. An ESM and an ESP. Load order is thrown right out the window and the end result is a whole lot of people complaining about this or that being broken and how everyone is filling up their active slots with duplicate files for no good reason. If you don't think people won't complain about it, you haven't been paying attention to comment threads.
Also, the "solution" can't be effectively carried out without the ability to generate ONAM lists. There's simply no way around that. The CK doesn't generate these. There are no existing 3rd party tools for Skyrim that do either. The only suggestion that's ever been offered is to use FNVEdit to generate them, but you run the massive risk of corrupting your whole file by subjecting it to a tool designed for Fallout.
TESVSnip isn't even safe to use anymore now that the CK has changed the format of the killcam records. That had implications down the line for a lot of other mods that seemingly shouldn't care. TESVSnip also doesn't properly handle record compression, nor does it save mods with a valid version header. So there are in effect no outside tools one can safely use to get by.
This is all compounded greatly by Bethesda actually fixing things and then never providing a changelog of it when they do. The last CK update corrected some bugs, but nobody would ever know that if some of us hadn't noticed it. The unofficial bug list needs to be completely rechecked now to see which issues are still valid and which aren't.
Not that it matters. In the end, if this navmesh bug isn't fixed, Skyrim's mod scene WILL deteriorate into the mess that Fallout 3 became.
