Sorry, there is no log as it didn't crashed the game/server.
The only thing I can see in the server's command prompt windows is this:

[Galacticraft] Found matching world name for Moon
[Galacticraft] Registernig remote planet dimension: -28
[Galacticraft] Registernig remote planet dimension: -29
[Galacticraft] Server attempting to transfer player gtfodude to dimension -28
[STOUDT] Sending serverside check to: gtfodude
[Minecraft-Server] gtfodude blew up
[Minecraft-Server] gtfodude moved too quickly! 0.0,399.27911206618853,0.0 <0.0,399.27911206618853,0.0, 0.02444881463122516>

Thank you for taking a look at this, this bug is game breaking for my friend and I.
