For blueprints with rails it appears that always 1 chain dock ends up in the ship core (which is default position if it can't find anything to attach to).
Sometimes that does not happen but you'll get a client nullpointer instead and crash. when you come back that 1 chain is gone.
Sometimes it duplicates a part of that chain and puts it on another random chain, the original chain still ends up where the shipcore is (or causes a nullpointer)
Blueprints with those issues:
{F81}
{F82}
Nullpointer:
