On a swept wing aircraft if both wing tip sections lose lift simultaneously the aircraft will
- yaw uncontrollably.
- pitch nose up.
- pitch nose down.
Explanation from PART66Online
On a swept wing the tip sections lie aft of the centre of gravity, so when both tips lose lift simultaneously the centre of pressure moves forward. This forward shift of lift creates a nose-up pitching moment. The behaviour is symmetric, so it produces pitch rather than yaw, and the direction is nose-up, not nose-down.

Yeah you got it. On swept wing tips sit behind CG, when they lose lift the CP shifts forward and nose pitches up.
