You'd need to ask Austin as he helped with that. I do not play EET or BGT (when using old games, before EE got published) thus I never really needed Worldmap mod. Remember, though, that there is a certain order needed. As mentioned in Southern Edge:

Compatibility notes: the mod updates existing mapicons.bam file; if you're using a mod that overrides mapicons.bam instead of patching it, it should be installed before the mod. BP-BGT Worldmap, which is always installed in the end.

So if there are problems, make sure that the order is ok first
