That is indeed strange. Beyond the motor controllers dual-lighting, were there any other significant and visible issues you noticed? Was the robot signal light responding correctly? Was the driver station reporting communication and code? Is the issue persistent or was it a one and done kind of error? Was your pneumatic breakout showing signal changes if you tried to actuate any of the solenoids?

My apologies on the large quantity of questions; anything from the driver station to the PWM connection to the motor controllers could have failed (unlikely but possible). The more information the CD community has, the faster the issue can be identified.
