From what I understand a lot of people have been blowing up Jags this year. One cause that I heard was common was that when you sent either a 1 or -1 value from the joystick to the motor the jags would blow up. Although this was an easy problem to fix (just set the values to .99 and -.99) our team opted out of using the jags this year because this was all unknown and we figured "why not use the extra victors we have lying around while we still can."
Hope I could help
