One of my players reported the same issue yesterday but I haven't been able to confirm it yet. I do not use extraplanets.
I think in my case it's probably sponge related as I see in other issue.
So it seems to be related to Sponge, as I can't recreate it in vanilla and you're both using Sponge. Did either of you notice it break after updating Galacticraft or Sponge? E.g. was it working in X version?
I installed both at the same time. I have removed sponge again for now. I have little time to play atm, so I'm just trying to keep the server floating.
As far as I know, nothing was updated before the issue started. The issue began, and due to this, the server's Extra Planets was updated. Also as a side note, the bug does not happen in singleplayer.
I have the same issue and looking for solution(exept i have not Extra Planets ). On my server i cant launch to the moon or other planet and map looks the same. In single player everything is ok. I also have installed sponge on server.
This version of sponge resolved issue, i cant fly to the mon now. But map still does not work
