Ship becomes unstable after sharing amount of inertia tensors
Reported
The ship I've been building has 16 pistons, if I share the inertia tensor on over approximately 10 of them the piston heads seem to completely bug out, detach and cause damage, flying about seemingly randomly while the entire ship rolls wildly, but yaw movement is ceased. Without sharing the tensors, the ship rotates on its own along the yaw axis. The blueprint files are attached if it helps, but I had to upload them as .txt files, so will require renaming.
I have the same bug 
Update, tested this on another ship, it appears that it's absolutely to do with the amount of shared inertia tensors enabled on pistons with heads.
With the H-1 Industrail Corvette blueprint from the workshop I can place any amount of pistons I want, but when I enable share inertia tensors on more than 5 pistons the bug occurs and all the piston heads fly off along with the ship vibrating rapidly until they've flown off. They fly off all the pistons, not just the ones with inertia tensors enabled.
I then tested it on a flying beam, and it appears that I need to have 8 piston heads attached to pistons with shared inertia tensors for the bug to occur.
This bug also doesn't seem to apply to static grids, which work fine.

Hello, Engineer!
I can't open the blueprint files provided by how they have been saved. Can you please attach them without converting them to text files?
You can access your blueprints files by typing %appdata% into your Windows search bar and you will be redirected to the hidden Roaming folder. After that just follow: \Roaming\SpaceEngineers\Blueprints. Select the correct folder where your blueprint is saved (local or cloud), zip the file and attach it here.
Kind Regards

Hi Laura,
I would suggest opening AAAAA_2 in zero-gravity as I was using modded conveyors when I built it, so I've had to quickly tape everything together using vanilla conveyors which has caused most of the ship's thrusters to not work. I can confirm that the bug still occurs though.
I've also attached a smaller ship, which was built in a completely vanilla world that has the exact same issue.

Hello, Solid Snake!
Thank you for these. I have found that AAAAA_2 causes the issue but you said this originally had modded conveyors. The Piston Test which was free of modded blocks does not seem to cause the issue for me. Are there any obvious steps I should take to reproduce this issue? I just want to make sure I can create the issue with something that never had modded blocks :)
