I did a play test of this change.
Started a new campaign, and saved the game.
The game loads normally, and when launched the ship has yaw controls.
So, that indicates to me that the Llama is properly loaded from a saved game.

From a playability point of view, this is a good step in the right direction.

I was able to complete the training mission, almost.

Setting max speed in maneuver mode is still not enough to satisfy Oswald's requirements, and I had to set travel mode to gather enough speed to pass to the next step in the training mission.

Oswald's last instruction was to purchase a jump drive and then get back to him.
I was not able to purchase the jump drive, despite there being one available on Atlantis, me having enough money and upgrade space in the Llama.

Another thing I noticed was that the fuel burn rate was quite high, and just doing the training mission used about a third of the fuel in the Llama.

After doing a refuel and repair, I also noticed that the fuel was not, in fact, refueled.

The issues noted here I am assuming that it is somewhere else in the code, and I have no problems approving this fix to go in ASAP.
