For those who have named planets and wildlife in the game, might want to go and check to see if those names still exist due to a supposed data erasing bug being discovered.
Apparently the bug only affects the oldest stuff named in the game and might be due to an unknown limit for name creating or game itself auto-removing old custom names after a while. Although some speculation about the people being affected were those playing before the game's official release.
