Describe the Bug

Secondary contraptions, as in contraptions attached to other contraptions, get inexplicably deleted when you save and leave a world. When reloading the world, the contraption is permanently deleted.

Reproduction Steps

1. build a contraption attached to a mechanical bearing
2. build another contraption attached to a mechanical bearing, but place this bearing on the first contraption
3. power the first bearing and watch both of the contraptions rotate individually4.
4. leave the world normally
5. rejoin the world the see the second contraption is completely missing

Expected Result

obviously the second contraption should not get deleted for no reason
