I originally found this bug before 1.11.0, but I reproduced it on 1.11.0.3045.

When decoupling a part or undocking, the BZ-52 seems to bug out and cause parts of a spacecraft to lose all gravity effects. In some cases it causes docking ports to behave as if they are still docked even after undocking.

The first two videos show the docking ports bugging out when detaching. The first two videos are reproducible only after attaching 2-3 cars to the lander can. The save file should have all the components necessary to reproduce this.

After the 1.11.0 update, I decided to try and roll back to before my spacecraft even landed. I hoped that maybe rolling all the way back would reset the environment and prevent the bug. Instead, I found a similar bug where detaching platforms while the dropship is landing will cause the cars to freeze in mid air and lose all gravity effects.

I suspect this issue is partially caused by the fact that I have BZ-52 points embedded within the middle of each car. I did that to facilitate mounting to the landing modules, but if there is a superior way to accomplish this mounting I would love to know about it. It wasn't a problem until recently. Again, I started experiencing this bug a couple days before 1.11.0.
