just change the 3 numbers (like 929 for R15 snowbrains) to:
800-865 for custom faces that have been used in nod that were NOT created by Glitch (Thorin's is an exception but when it was created it wasn't intended to be a face)
300-350 for custom faces that were made by Glitch.
1-299 for the basic 300 faces anyone can use.
