If you read the file: http://www.fallout3nexus.com/downloads/file.php?id=8069 it says you must place the esm after broken steel.
But with this one: http://www.fallout3nexus.com/downloads/file.php?id=10045 I have to place it after the esm, and it is an esp.
So FOMM resets the esp back to after all the esms.
Confusing, I know, but I can't explain it any better. Can anyone help, like disable this?
