Plugin Disabling Itself

[arttwart]

Holographic Placeholders plugin disabling itself with Sport Paper. I contacted to developer of the plugin and he said: "Your fork of Spigot apparently doesnt have all the functions, my plugin is only supported on Spigot and original Paper. Not forks of them."
org.bukkit.craftbukkit.v1_8_R3.CraftServer.getOfflinePlayers

Error: https://sourceb.in/E3Kox7JUVZ

Is that means, I won't be able to use it forever or are you going to fix this?

SportPaper does not modify the getOfflinePlayer method in CraftServer. So the error you're running into is not SportPaper specific. In this instance however it looks like your playerdata directory in the world folder is empty which is what seems to be causing the NullPointerError.
