Subgrid Klang Issues after 1.210

Hello,

I am experiencing massive Klang issues with multiple subgrids on a fairly large build. Before the update, it was very stable. After updating, several, but not all subgrids detach on world load. I understand that there is new physics behavior after every update, but this Klang issue is fairly extreme!

I have confirmed this by rolling back to the 1.209 version via Steam's Game Versions & Beta option in the state where I was working on this build yesterday, where this world loaded the large ship without issues. By checking the entity list, I saw no loose subgrids.

I then re-updated the game to 1.210 and loaded the save again, and the subgrids once again detached on world load.

Interestingly, the subgrids that detach are more likely to be pistons, but some hinges are affected as well.

Some things I have tried:

1. I have used SEToolbox to edit my save and zero out the LinearVelocity and AngularVelocity of every grid, but the same subgrids detached on world load.

2. I rolled back to 1.209 and minimized the forces of every piston, and set every Inertial Tensor option onboard the construct to OFF, but the same subgrids detached on world load in 1.210.

I would like help to at least get this build in a state where I can continue working on it again without the detaching parts on world load, as the detachments break many action toolbars that would be very tedious to manually restore.

I am providing a copy of the world's SANDBOX_0_0_0.sbsB5 if it would be helpful for investigation. I noted that this support site rejects Space Engineers blueprint and worldsave filetype attachments, so I renamed a copy of the .sbsB5 file to .txt, please change the filetype back to .sbsB5. (If there is a proper way to upload SE files for investigation, please let me know.)

A summary for investigators: Please note that this attached world loads without subgrid detachment in 1.209, whereas many subgrids detach in 1.210.

Thanks,

- K.I.
