Ship suddenly stops responding to movement controls, drifting uncontrollably through space.
Suddenly two of the thrusters were constantly burning, using a lot of hydrogen, the ship couldn't turn or move at all, turning the thrusters on and off did nothing either. Tried leaving and rejoining also didn't help. Eventually, we got it fixed by cutting and pasting the ship back in. That's the only way I've been able to fix that issue so far.
It's worth noting that the ship had hydrogen in the tanks, was powered, and was previously moving fine before this issue occurred.
