I've built numerous small grid ships, both via Blueprint and from scratch, that either right away or after some use will be completely unusable. The ship either rubberbands to the ground, drives itself all over the place, sometimes doesn't seem to be a real grid at all, or only some components appear to exist. When the ship is created, and you hear the engines fire up after attaching batteries, all the ships engines are rotating and working. Then later, you can look at the ship and everything is stopped. Dead. But you can partially control it. So many funky things going on it's hard to explain. Do I have bad game files or something?
