Checked everything, no traces of anything wrong yet the ship is unable to move.
Yesterday I made a new game, this time conventional. Quickly designed a conventional survey ship, it was moving (with 1-5 day pauses before moving, I figured it might be differences in engines or something) for few months and now it's stuck in open space mid flight to Earth. There's nothing wrong with it, it just displays that it moves but it's not. How ever many order reset and TF, TG shuffles I do it's just stuck there.
I'm starting to wondering if it's a software problem and I have to reinstall the game but it's just ridiculous.
EDIT: Disregard it, I split the TG and only then the ship started moving. I have no idea why would it work a little in the first one and then only continue in the new. I will play around with it and will try to figure it out. Is there something about ships in Shipyard TG not being able to do orders?
