Ah well, that settles it. I didn't notice cuz the first time I played the game (I'm new as you can see), I got beasts very early so lifted the restriction.
The editor & girlsx files are driving me nuts although. I don't get it - I gather pictures, set a folder named after a girl (Gianna Michaels for instance), open up the editor, edit stuff, name the file Gianna Michaels, then save a girlsx file. What am I doing wrong? lol.
