NoMoreAdsNorPhantoms

Bukkit/Spigot plugin that hide Advancements/Achievements of players and disable the spawning of Phantom mobs (introduced in Minecraft 1.13).

Created for a UHC server (using the fantastic UhcCore plugin) where just these features were missing.

The plugin is very light and simple, without stats or configs. This is the only file with all the source code:
