I think the quirks are messed up on the Addar in mechlab. Not sure if it's a UI error or a gameplay error.
Steps to reproduce:
1. Strip LA, RA, LT, and RT omnipods from all three variants
2. Use the popup to show the Adder's base quirks
3. Observe that the Prime has a 132 Yaw angle and 144 d/s speed
4. Adder A has +12 degrees torso yaw angle and +10% yaw speed
5. Adder A shows 132 Yaw angle and 132 d/s speed. This should be 144 and 158.4 respectively
6. Adder D has +6 degrees yaw angle and +20% speed
7. Adder D shows 138.6 yaw angle and 168 d/s speed This should be 138 yaw and 172.8 d/s speed.
I'm not sure what the problem really is but something just doesn't make sense to me here.
