Wildstang apparently lost one yesterday as well. Same failure case as Beatty and others - only 1 direction works. After a few minutes of making fun of software for having bugs (

) we realized the Jaguar LED was lighting up but the motor was not moving. It was at the end of the meeting so we didn't do much more, but we'll be pulling it off the robot at the next meeting to do some bench tests to confirm our diagnosis.
As for how we've used it, it was freshly installed on our never-been-driven prototype and was not working the very first time we used it. We think it may have been used on a prototype drivetrain we built in December, but we had only used that prototype lightly - certainly never putting it under any serious strain.
We already distrusted the Jaguars enough based on what we've heard here that we weren't planning on using them on the drive wheels, but we thought we'd give them a shot for use in some lower-current situations. If we confirm that this incident is definitely a Jaguar failure we'll almost certainly avoid using them this year. No RMA policy can make up for the loss of an important match.
