I've been modding since Morrowind so I just jumped in and started messing with it. Figured with knowledge of Oblivion and Morrowind's modding tools that I would be fine but ran into issues with Navmeshes, researched it, and ended up here.
But thanks for passing the blame on to me. Stay classy.
The point is that the issue has been documented in several places, all of which are associated with "learning the CK," which is what you said you were doing. That being the case, is it Bethesda's fault that you did not see it?
Also, your note on the wiki is all the way at the bottom in the place least likely to be seen by people that might be cherrypicking data from the wiki (which is the type of browsing a wiki is DESIGNED for)
It's where "Notes" are usually placed in a document. There was a link called "Note" at the very top of the page in the contents box. For the sake of clarity, I have renamed it to "Known Issue". And now that I see that EmptyK has posted that a fix for the problem is in the works, I have updated the message accordingly, there and the other places I put it.
