Both Ailerons Failed Simultaneously

We are flying a fixed wing aircraft using the albatross airframe since it is a V-tail. We used a Y connector for the ailerons instead of plugging in aileron left/right in channel 1/2, so we just had the y connector attached to channel main 1. Could this be a problem? Anyway, we were just flying a loiter mission when both aileron servos failed at the same time. We debugged this issue and all the cables were fine, along with the channel on the pixhawk. The only hardware failure was both servos shorting, since we could still move the motors manually. I’ve uploaded the ulog, you can see the actuator output for the ailerons go to max just before we tried to take it over in manual near the end of the flight.
