Describe the Bug

Assume we have two mechanical bearings A and B, with their respective contraptions a and b. If B is in a and A is in b, when we rotate A, contraption a (including bearing B) will get deleted without drops.

This is different from #3831 - the destroy structure will not drop, and it is destroyed for completely 'no reason', not because of being overlapped by another contraption.

Reproduction Steps

1. Place a contraption A, and connect it to a large contraption a.
2. Place another contraption B inside b.
3. Make A a part of b.
4. Use a hand crank to activate A.

Here we can see the whole a is deleted, including B.

Expected Result

Since b could be viewed as a secondary contraption of A, the structure is illegal. Expected behavior could be:

• Bearing B breaks,
• Bearing A does not spin its contraption, giving a 'Failed to assemble' error, or
• Bearing B and its contraption works correctly as the secondary contraption of A, but A stays unmoved.

Additional Context

It is a natural question that what will happen when N bearings connect to each other in a loop. Actually, things will break when N≥2, but seemly not always when N>2.

Since some players are utilizing this feature for fun, it is advisable to add a config option which unfixes it, once it is fixed.

This is like the most confusing issue I have ever seen.
You could post a video to make it clearer.
