Last night I attempted to "restring" a CTVT bosy I have that broke by using a set of replacement rubber bands/elastics also purchased from CTVT. It's the first time I've had to do something like this and I believe I did it the way I was supposed to, but when I got the body back together it was extremely loose. Every appendage was so flimsy, the body had absolutely no firmness to it whatsoever. What did I do wrong?
