Walkthroughs for custom maps.

Until the author sits down and tests the map from start to finish, I don't see the point in writing about the bugs found.

That's a harsh condition :D. I think that providing a list of bugs is the least that players can do; it would also make the author's task easier if they decide to do a full test in the future and make the map less buggy if someone wants to try it out in its current state.
