[18:10:56] [Server thread/ERROR]: #!#!
[18:10:56] [Server thread/ERROR]: #!#! Something went horribly wrong with Skript.
[18:10:56] [Server thread/ERROR]: #!#! This issue is NOT your fault! You probably can't fix it yourself, either.
[18:10:56] [Server thread/ERROR]: #!#! It looks like you are using some plugin(s) that alter how Skript works (addons).
[18:10:56] [Server thread/ERROR]: #!#! Here is full list of them:
[18:10:56] [Server thread/ERROR]: #!#! skRayFall (http://sk.rayfall.net/) LiteBansSk (https://github.com/Pugabyte/LiteBansSk) SkriptJSON skript-mirror TuSKe (github.com/Tuke-Nuke/TuSKe) SkQuery MundoSK (https://forums.skunity.com/resources/mundosk.69/) Skellett (https://forums.skunity.com/resources/skellett-the-addon-with-a-beast-name.24/) Reqn ExertSK
[18:10:56] [Server thread/ERROR]: #!#! We could not identify which of those are specially related, so this might also be Skript issue.
[18:10:56] [Server thread/ERROR]: #!#! You should try disabling those plugins one by one, trying to find which one causes it.
[18:10:56] [Server thread/ERROR]: #!#! If the error doesn't disappear even after disabling all listed plugins, it is probably Skript issue.
[18:10:56] [Server thread/ERROR]: #!#! In that case, you will be given instruction on how should you report it.
[18:10:56] [Server thread/ERROR]: #!#! On the other hand, if the error disappears when disabling some plugin, report it to author of that plugin.
[18:10:56] [Server thread/ERROR]: #!#! Only if the author tells you to do so, report it as Skript issue (url below)
[18:10:56] [Server thread/ERROR]: #!#! Issue tracker: https://github.com/bensku/Skript/issues (only if you know what you're doing!)
