Problem/Issue:

Any attempt at going to space with Galacticraft ends up timing out the server. Whenever a player launches a rocket, the following: https://gist.github.com/spruill7716/6b32cff2ea7bccae9744cfce2d4b205f is spammed in the console and overloads the server. I saw mentions of Flan's Mod in there, and think it may be some kind of conflict? I've submitted a report on their GitHub as well for safe measure.
