After (too) many attempts and several exchanges with Poser's technical team, I've decided to abandon clothing simulation in Poser 14. I will continue to create clothing for Poser, but without guaranteed compatibility with Poser 14; some work, others don't, and my enjoyment comes from creating according to my imagination—I'm an artist, not a technician. Therefore, they will be marked as compatible with Poser versions 6 through 13.
