Hi, Skript isn't working for the 1.12.2 server. It's not in the right version and, although in the version I'm about to send you it says "old version, ..." the version is the latest one that is working.
This is the link for the right version: https://github.com/SkriptLang/…ownload/dev37c/Skript.jar
hope you're going to do something about it
