Dampers stability issue with Docked Ship

Description:

Active ship begins to pitch up or down, then starts rolling uncontrollably when dampers are active, thrusters are engaged and a second ship is connected (docked), such as a cargo ship with a mining ship piggy-backing.

Steps to Reproduce:

1. Dock two ships together. Ideally of near equal mass.

2. (Optional) Turn off [Y] the second ship. (See note)

3. Enter the cockpit of the primary ship and fly forward [W] with Dampers [Z] active.

4. Issue is especially evident (catastrophic) at 70m/s with the ship I used.

5. (Alternatively) With Damper OFF, accelerate to 300m/s and turn Dampers ON to slow down.

Note: While the issue occurs either way, turning off the second ship makes it far worse, likely due to having less gyros active. However, this also proves that it is not the second ship that is trying to negate the first ship's movements through it's own thruster and gyro inputs.

Expected Result:

Fly Straight

Actual Result:

Uncontrollable roll-over / looping.

Possible Cause:

This appears to me as a physics issue where the second ship's mass is not calculated for the purpose of finding the center of mass, resulting in the center of thrust to be misaligned from the combined center of mass, resulting in rotational force being applied.

Environment:

- OS: Linux Pop!OS

- Version: Space Engineers 2.2 (was also in 2.0)

- Platform: Steam

Reproducibility:

Always

Severity:

Minor, as workarounds are available. But definitely something to be fixed as more players build bigger and more complex ships / Carriers / Drone ships.

Workaround:

Fly with Dampers off and only turn them on for the last few meters per second of deceleration. Pulsing Dampers on and off to maintain stability also works, but less effective.

Additional notes:

This issue was tested exclusively in space. The ship has all 3 engine types equipped and is capable of both Atmospheric and Vacuum flight. Atmospheric environments are expected to produce the same issue, but have not been tested. Effects proportionally diminish when the mass of the primary ship exceeds the mass of the docked ship.
