what is LEO.MIX? There is no such mix in game.dat, so i doubt that the game reads this.
Which mix files do you have in your TD directory? For example, if you have an SC004.MIX too, the missions in this one would overwrite missions in SC003.mix with the same name.
Make sure that your SCXXX.mix file has the highest number, then it should replace all missions with the same name (even the original).
You also can't have more than 80 new missions for each side because only missions scg20ea.ini/bin-scg99ea.ini/bin and scb20ea.ini/bin-scb99ea.ini/bin appear in the "New Missions" menu of the expansion pack.
Oh and welcome aboard.
