Added

• Version 50 moons were finally added to the LevelTypes enum.
• LethalLib weathers now also get added to LethalLevelLoader moons.

Changed

LethalLib [0.15.0]

Added

Fixed

• Enemy and item spawn weights now get applied as one would expect
  • Levels.LevelTypes.All no longer overrides all spawn weights
