[ERROR] #!#! Something went horribly wrong with Skript.
[ERROR] #!#! This issue is NOT your fault! You probably can't fix it yourself, either.
[ERROR] #!#! It looks like you are using some plugin(s) that alter how Skript works (addons).

[ERROR] #!#! We could not identify which of those are specially related, so this might also be Skript issue.
[ERROR] #!#! You should try disabling those plugins one by one, trying to find which one causes it.
[ERROR] #!#! If the error doesn't disappear even after disabling all listed plugins, it is probably Skript issue.

[ERROR] #!#! On the other hand, if the error disappears when disabling some plugin, report it to author of that plugin.
