Seems sometimes upon moving from one world to another I get disconnected from the server with the message "Internal Server Error". This seems to happen randomly depending on which planet. It seems that Europa happens a lot more than others.

Versions:
Minecraft 1.7.10
Forge 10.13.4.1614
Galacticraft 3.0.12.501
GalaxySpace 1.1.5
(Number of other mods I honestly don't feel like listing. Here is the full server/client start up log:
