I have tried everything [well almost everything] to get the buildings and other objects to show up in Balmora in the CK [only a few HH doors show] and some other places have the same problem,but most of it is fine in the game.
If I remember correctly some towns [cell blocks] had thier own WRLD in the old morrowind CS,and am thinking that those CELLS were not converted over with the rest of wrld_morrowind by the converter.
If not then it is going to be real hard to add and edit detail in those regions.?

Did Morroblivion have this
Did Morroblivion have this same issue? Or was everything converted over properly for them?
