g'day and welcome!
You will find all us map makers are a bit crazy! But hay, someone has to do it!
To answer your question..
Those areas are nothing to do with the static files or the map0.mul. OSI in their wisdom patched them on top of the map. To remove them you have to remove all the mapdif files in your UO folder.
I cant remember how many there are..
Mapdif0.mul
Mapdif1.mul
Mapdif2.mul
Mapdifl0.mul
Mapdifl1.mul
Mapdif2.mul
hmmm I thought there were 8 of them..
Anyway, thats what you are looking for.
Hope this helps
