Well, if the approved tutorial is not working it IS related somehow to noggit. If there wouldn't be any error, we'd drown in custom user made maps already but that seems not to be the case. A fresh tutorial is required or a proper explanation why this is not working properly, even when it is done by hand.

I disagree with you on the user's part. I don't think the wow modders are made up of people who don't care about the editing programs they use. First off it is everyone's(developer+user) interest to have a bugfree program to use therefore reporting encountered bugs is not a favor to do, as long as there is a clear method doing it (I'd prefer a forum section where bugs can be posted as topics as opposed to the current bugtracker method [too "developerish"] ). I don't see a reason why would a user leave an annoying bug unreported when he bumps into it each time he uses the program. Even though I think modding wow requires a lot of understanding (thus expert people), there will be always newbies or people who simply don't understand things easily. To that end there should be a built in help menu or something, and a link pointing to this forum (even I had hard times finding this board) so people can get help easier and/or report bugs.
What discourages people here is the pressure to report bugs. In a working community this shouldn't be needed as per the reasons explained above.

The log file tells only that the program has opened my custom .wdt file and then the log ends. Nothing useful in it. I tried to use adt from other continent but it does not work. The difference between manually created map.dbc and generated map.dbc is that the generated fills out a lot of extra coloumns with the continents/instances' string IDs whereas the manuallly created has 0s written in there. AFAIK this shouldn't cause error, nor influence how the file works (However to safely state that I'd need to know what all those coloumns are for exactly).

It would be good to know how to create a continent which does not crash the editor (and the game). Following the existing tutorials does not seem to work. On the top of that I do not have another options to try world building besides noggit, because YiasEdit DX comes with an awkward launcher which tries to download the actual program and...fails.

Yea I know that anyone can apply for the test group but a known fact is that people are lazy in general which means even the smallest step required to get stuff discourages them from doing so. What I am saying there is that if the betas would be really public accessible(and not "semi-public" like now) then more people could volunteerly help to catch bugs.
