No Zombify Piglin

A simple plugin that prevents piglins from becoming zombified piglins in the Overworld. Piglins that were spawned with the plugin installed will not turn into zombified piglins after the plugin is uninstalled, and piglins that were spawned before the plugin was installed will still be vulnerable to becoming zombified piglins. This plugin also prevents piglins from becoming zombified in the End as well.
