Heyo! Just encountered a weird one: For whatever reason, when I tried to export a PSD "without face," Mannequin was having none of it. It stayed on "0% exported" and just froze up. When I tried to force the program to close, though, I was able to export a full PSD after I got the "do you want to close without saving?" message (I told it no and the program was working fine again after that).
