Everytime I try, it tells me this-Legacy plugin Fireball v1.0 does not specify an api-version. [11:55:52] [Server thread/ERROR] : Fatal error trying to convert Fireball v1.0:me/electcheese/Fireball/Main.class org.bukkit.plugin.AuthorNagException: No legacy enum constant for FIRE_CHARGE. Did you forget to define a modern (1.13+) api-version in your plugin.yml? Just for the record, this is what my YML looks like-main: me.electcheese.Fireball.Main name: Fireball version: 1.0 author: electcheese api-versions: 1.13
