Airfoil inversion setting lost at stage 1 ignition

Wing set to Radial x2
Input: Yaw (this defaults one side as Yaw 1 with the other as Yaw -1, this causes them to move in opposite directions and roll the craft, not what I want)
Break the symmetry between them
Invert airfoil on the wing that has Yaw -1 which turns it into Yaw 1
Both wings now have Yaw 1
Launch, test on pad before ignition, wings act as I want. Yaw input makes both control surfaces move in the same way.
Press space to ignite engines.
Now the wings have changed back to going in opposite directions.
