[21:04:29 ERROR]: #!#! [Skript] Severe Error:
[21:04:29 ERROR]: #!#!
[21:04:29 ERROR]: #!#! Something went horribly wrong with Skript.
[21:04:29 ERROR]: #!#! This issue is NOT your fault! You probably can't fix it yourself, either.
[21:04:29 ERROR]: #!#! It looks like you are using some plugin(s) that alter how Skript works (addons).
[21:04:29 ERROR]: #!#! Here is full list of them:
[21:04:29 ERROR]: #!#! skRayFall v1.9.28 (https://sk.rayfall.net/) Skellett v2.0.7 (https://forums.skunity.com/resources/skellett.24/) SkQuery v4.1.7
[21:04:29 ERROR]: #!#! We could not identify which of those are specially related, so this might also be Skript issue.
[21:04:29 ERROR]: #!#! You should try disabling those plugins one by one, trying to find which one causes it.
[21:04:29 ERROR]: #!#! If the error doesn't disappear even after disabling all listed plugins, it is probably Skript issue.
[21:04:29 ERROR]: #!#! In that case, you will be given instruction on how should you report it.
[21:04:29 ERROR]: #!#! On the other hand, if the error disappears when disabling some plugin, report it to author of that plugin.
[21:04:29 ERROR]: #!#! Only if the author tells you to do so, report it to Skript's issue tracker.
