I also experienced this yesterday, paused for around 1hr15mins, went into a mad pitch up - trim was like 85% up. Had to fight to recover, but did. Also - I'm a pilot on QVirtual - the SMARTCARS system recorded a reduction in fuel, not typical.
I have Airbus Thrustmaster Joystick and Throttle Quadrant (just the main one, not the add ons).
