Hello, this is a public service announcement to those that are having issues with Skellet. When getting the ch.njol.skript.SkriptAPIException: No class info found for citizen error, follow the steps below to hopefully resolve the issue.

1. Make sure you have the latest version of Skellet found at the top of https://github.com/TheLimeGlass/Skellett/releases
2. Install the Citizens plugin from https://ci.citizensnpcs.co/job/Citizens2/ and make sure it is the correct server version

  Npc: true
  # If you use CorpseReborn https://www.spigotmc.org/resources/corpsereborn.29875/
