find all the files that related to those 2 maps (75,76) which i think it will be the interface/world files .... then Rename those files to map 102 and 103 if you are not using them ( 75 = 102 , 76 = 103 )
then add them to your client (delete the 103-102 map files so it don't mixed up with the new ones you adding) and rebuild your client data . that way you will have your minimaps working and the maps working fine
you can try to patch them to your client , but you might get SGraphics when u move to them , because there are already existing files in those 2 maps 102-103 (original ones)
by doing that (if patching didn;t work with you and the building data worked) you will have to let your players to download the new client you made so they are able to get into those maps
