Yeah, I also had this problem. When I went to the room inside the large wreckage, there was nothing inside

It is more than just empty rooms in wrecks, if you relog it fixes the empty rooms. What you cannot fix is the fact that no wreck in my game has any prawn arms, no thermal reactor, no nuclear reactor, and the rest of the fragments are bound to wrecks. I am hosting a server for me and my friends and this is getting in the way of progression, thank you, and have a nice day.
