I was curious about this actually. I recently started playing the game and made a couple maps with the Galaxy Forge 3 software (which was pretty simple enough to use) but whenever I even change to the appropriate tab (in game) it crashes my game. If I remove the created files from the folder, it never crashes so I am pretty sure their presence is causing it. Any thoughts?

This thread is out of date. Maps made with Galaxy Forge 3 are no longer compatible. You'll need use the new Galaxy Forge or try to update them to GalaxyForge 4 format, a tool by Harpo up there maybe able to do this.
