Hi, anyone has an idea how the ship is determined, in which i start if i join my game? I saw a lot of different suggestions on the steam, so i thought i better ask here before building a new ship ;) first suggestion was: ship is defined alphabetically, first letter in alphabet is stating ship. Worked pretty well in the beginning, i renamed my miner to "XX_(Number) Miner" and always joined in my Main Ship. But now it dont work anymore, since i build a new ship with a "lower" letter as the first letter. But this ship was only one block for testing purposes. when i rejoin my game i still start with my Main ship, and not with my test ship with the lower letter. second suggestion was: ship is randomly choosen from all your ships in the sector. This seems wrong too, since i rejoined my game about 6-7 times and i always started in my Main ship (i had 3 other ships in that sector) Is it possible, that the starting ship is determined by the ship volume (ship value?)?
