Internal error when using /skript reload scripts after 1.12 update

[RobotnikMan]

Skript Version: Skript v2.2-dev29
Skript Author: Bensku
Minecraft Version: 1.12

Hi, I am getting this error after the 1.12 update when I try to use the command /skript reload scripts, and none of my skripts work. When I use the command in Minecraft it says 'all scripts reloaded without errors', then says 'an internal error occured while attempting to perform this command'

Here is the error in the server console

[16:36:16] [Server thread/INFO]: RobotnikMan issued server command: /skript reload scripts

I know it says something about WorldGuard, but I have the latest version of that installed as well
