Known Bugs:

If a player enters one of the new biomes and any of the new music is played, it will be played for all players, regardless of the biome/dimension where they are located.

The new status effects are removed once the player disconnects from the game, that is, if they reconnect they will not have the potion effects added by this addon.

If you close the world and an entity had a new status effect, when you open it again the entities will not have the effect, they will have been removed

The new status effects appear as an Action Bar, they do not have their respective icon in the inventory

Credits:

"Happy Bro": suggested adding a Mangrove-type biome to the Nether, thanks to that idea I was able to create the Shady Mangrove Swamp!

Mineking8121: suggested adding that Endermites spawn naturally in the Shady Mangrove Swamp!

Bloxurlo: reported many bugs such as: the blocks dropped their items even when destroyed in creative mode, the stairs, fence and fence gate were not displayed correctly in the inventory interface, among others!
