I worked 3 days on erasing Bi vanilla units; with these text files you'll have only the essential units and so you can add all your new units without pass the units limit ( i think it's 200 or 250)

here the download link with the text files:

copy it in you BI\data folder

hope it will be useful for all of them who want to start a new modification
