Hi, today I downloaded skRayFall and when I loaded it, it displayed a long error in the console, it appears in the plugin list but when I load a skript with effects that are from skRayFall they do not work.
Here is the error:

Server information:
Version: 1.11 (Spigot)
Skript version: 2.2 dev 29
Java version: 8

Do this error occur when you go to start up the server or are you using plugman to load up the plugin after the server has been started up?

That happens when I reload it with plugman, but if I restart the server it displays the same error and effects dont work
