Guys I found the solution! It's the Torpedo Arm. I built a new Exosuit and had no problems, until I switched my upgrades to the new one. I then began experimenting what the problem was, and it's the Torpedo Arm! I am so happy I'm about to cry!
Yup me too. I got it when I tried to enter my Cyclops and sort of smashed against it and heard a loud bang. Then when I exited, it was tilted, and the Moonpool is fine, but then when I enter the Cyclops it happens again...
