Hey Kalisto, It looks like all of the FM locations were also in the TM locations category page. Is this what you are referring to?
The {{Infobox/Location}} template that you see at the top of all location pages automatically adds the page to a location category based on the |Region field.
for instance, the following:
{{Infobox/Location
|Region=Forlorn Muskeg
}}
will auto-add the page to Category:Locations in Forlorn Muskeg.... at least it should. Instead it was adding the page to Category:Timberwolf Mountain. I have fixed this.
