Celestial engine is going under a major code overhaul and integrating it better with PancakeCore which allows me to clean up chunky and awkward code in addition to fully updating to 1.17 whilst still supporting 1.16, if you have any suggestions for the plugin place them in discussion or my discord and i'll see what i can add for the newer releases!
Patch note : Changed the Planet pack biome to THE_VOID from END_BARRENS to stop endermen spawning in planet generated worlds
