PS: I don't know how to copy the entire webpage of Spigot for documentation, but here is the link:https://www.spigotmc.org/resources/epicworldgenerator-1-14-1-15-1-support-all-update-aquatic-features.8067/
Download here
Fixing...Fixed, I think, I don't know how to use NulledBB really, so I'm sorry if the link redirects to the spigot webpage :(
