Modpack version
Enigmatica 2: Light 1.4.5

Issue
I am running the game in singleplayer and sometimes open to lan to play with my mates.
When I launch the unmanned rocket to my space station, it always spawns at the bottom of the space like around y = 0. I have already put the docking pad on my space station. However, when I go to the space station with my rocket (manned rocket), it becomes fine and the rocket can be landed on the docking pad.

Thank you for remaking the issue :)

Do you remember whether the world was open to LAN during the unmanned rocket launch? Cause LAN worlds tend to have all sorts of odd issues.

Yes, i normally open to LAN all the time

Then that is most likely the cause :/ the chances of getting this fixed is close to 0 I'm afraid, issues I report to the Advanced Rocketry issue tracker are mostly ignored.

I've decided not to take this issue any further, as most modders no longer work on Minecraft 1.12, and development of Enigmatica is focused on Minecraft 1.15+ - I hope that's understandable :)
Thank you for helping to make E2E polished by reporting, I hope to see you in E5+!
