Good Afternoon, From what I noticed is when taking a rocket to moon or one of the other planets, overworld TPS drops to 7 from 20. It causes lag for everyone until the server is restarted. I had a thought of instead of taking the rocket out of the game or disabling Galacticraft altogether. To get to the other planets perhaps using the portal to the other dimensions such as the end. Make it a requirement to have the tier 1 rocket to use the portal to get to say the moon. Then in order to get to Mars you need to have the tier 2 rocket in that portal. Then you could make the rocket a non-placeable object. I have been using the enhanced charm of dislocation to get to these places and no one has reported any drop in TPS.
