Ahhhhhhh gaddangit VRC why'd you have to go and change jigglesystems in a way that always breaks all the old ones! Grrrr.
Thanks a bunch for the troubleshooting and for letting me know exactly what was going on :) Greatly appreciate it, and I really gotta find a free week once I finish commissions at long last to just sit down and upgrade allll the existing models @_@ so many of them.
