Addons: SkBee (I don't think it is relevant)
Extra Info:
The first time I try to move it, the script stops it, but the second time the script doesn't stop it. The third time, the script stops it, the fourth time, the script doesn't stop it. Etc.

every 0.01 seconds:
loop all players:
if slot 8 of loop-player's inventory is not nether star:
if loop-player's inventory contains nether star named "&aSkyBlock Menu &7(Right Click)" with lore "&7View all of your SkyBlock" and "&7progress, including your Skills," and "&7Collections, Recipes, and more!" and "" and "&eClick to open!":

# Prevent dissapear menu opener

on inventory click:
    clicked slot's name is "&aSkyBlock Menu &7(Right Click)"
    cancel event
    
on drop:
    event-item's name is "&aSkyBlock Menu &7(Right Click)"
    cancel event



# Add menu opener if dissapeared
on player's held item change:
    if name of (slot 8 of player's inventory) is "&aSkyBlock Menu &7(Right Click)":
        stop
    drop slot 8 of player's inventory
    set slot 8 of player's inventory to nether star named "&aSkyBlock Menu &7(Right Click)" with lore "&7View all of your SkyBlock" and "&7progress, including your Skills," and "&7Collections, Recipes, and more!" and "" and "&eClick to open!"



# Open menu

on right click:
    if player's tool is nether star:
        if uncolored name of player's tool is "SkyBlock Menu (Right Click)":
