The decision to use vanilla zombies over Citizens NPCs was intentional. Not every server has Citizens installed, so using vanilla entities makes the plugin more accessible and lightweight. However, since the plugin is open source, you're welcome to create a Citizens implementation as an optional hook! Feel free to fork the repo, implement the feature, and submit a pull request. This way, server owners could choose which implementation fits their needs best.
Version: 2.1
Extremely useful plugin! Developer is very friendly, responded quickly and fixed my problem very quickly :)
Great plugin for SMP/PVP servers that want a safe and fair way to implement spectator mode. Very comprehensive config and developer was highly responsive when I brought a bug to his attention, thanks magas!
Developer responded quickly when I had a concern and tested out the plugin on the same version I was using to see if it worked for him. Great support for a great plugin
