It came to my attention that the menus don't work when updating to 1.18.2. This is because of NBT-API errors that generate. To my understanding, these errors generate because of NBT changes the library I use isn't caught up.

I don't know when an update will be pushed to fix it. It may even be after March 15th. But until then, if you MUST use 1.18.2, please deny players from using the plugin's menus. Otherwise, if you're fine with going back to 1.18.1, please do so instead.

By denying players from using the plugin's menus, this means denying the following permissions for them:

• ultracolor.gui
• ultracolor.chatcolor
• ultracolor.namecolor
• ultracolor.command.gradientcolor (which will come out in the next update).

Players would then need to have permission for commands like /ucolor setchatcolor, which you can find in /ucolor perms. A new jar should hopefully be released within the next 2-3 days. Sorry for any inconvenience!
