Goodness. Shows how ignorant I am of the process, figured they’d have that stuff situated two days at most.
Very well, apologies for pestering, I’ll be patient.
I added the DLC files for download here as the DLC is free anyway. You still need to use the steam version but extract the 3 files here:
*your steam location*\steamapps\common\Monster Girl Factory\HCreatureCrafter\Content\Paks
and then run the game. I'll delete them from here once Steam approves the DLC
