Tank tracks mess up after dupe

[Rammelslakje]

Hello,

I'm working on a tank with realistic tracks.

I've stacked 20-30 plates and attached all of them with Adv Ballsocket so they move min 10 degrees and max 30 degrees which I require for the suspension base.

But whenever I dupe or save etc and I spawn it again it messes up and isn't aligned anymore.

Here is an example:

The one on the left is normal one, the one on the right is duped, saved, copied one. I've tried all options incl. weight and paste locations and angles but it always messes up and is not as stable as the original made one.

Any idea's? I don't want to make both the tank tracks from start everytime

Thanks

Looks like a pretty complex dupe.
I don't think anythings wrong.

What duplicator did you use?

Probably Adv. Dupe 1, 2.
