Regarding the DriveThruRPG print copy orders of the Maximum Mutagenesis book and any refunds you may have received:
There was a problem with the file that they did not let me know about until 30 days after the print version was made publicly available. I have been working with them and the problem should now be resolved. Once I receive a new set of proofs, the print version should be available to purchase again.
Sorry for all of the trouble.
