[14:40:02] [Server thread/ERROR]: #!#! [Skript] Severe Error:
[14:40:02] [Server thread/ERROR]: #!#! 
[14:40:02] [Server thread/ERROR]: #!#! Something went horribly wrong with Skript.
[14:40:02] [Server thread/ERROR]: #!#! This issue is NOT your fault! You probably can't fix it yourself, either.
[14:40:02] [Server thread/ERROR]: #!#! It looks like you are using some plugin(s) that alter how Skript works (addons).
[14:40:02] [Server thread/ERROR]: #!#! Here is full list of them:
[14:40:02] [Server thread/ERROR]: #!#! skript-mirror v2.0.0-SNAPSHOT (https://github.com/btk5h/skript-mirror) Vixio v2.0.4 (http://vixio.space) TuSKe v1.8.2-Pikachu-Patch-3 (github.com/Tuke-Nuke/TuSKe) skript-yaml v1.3.2 SkQuery v4.1.1 
[14:40:02] [Server thread/ERROR]: #!#! We could not identify which of those are specially related, so this might also be Skript issue.
[14:40:02] [Server thread/ERROR]: #!#! You should try disabling those plugins one by one, trying to find which one causes it.
[14:40:02] [Server thread/ERROR]: #!#! If the error doesn't disappear even after disabling all listed plugins, it is probably Skript issue.
[14:40:02] [Server thread/ERROR]: #!#! In that case, you will be given instruction on how should you report it.
[14:40:02] [Server thread/ERROR]: #!#! On the other hand, if the error disappears when disabling some plugin, report it to author of that plugin.
[14:40:02] [Server thread/ERROR]: #!#! Only if the author tells you to do so, report it to Skript's issue tracker.

what is the code you are using that throws this error?

[myavuzokumus]

on break of diamond ore:
	if player's tool is not pickaxe:
		cancel event
	else:
		cancel event
		if {sctaskaz::%player%} is set:
			damage player's tool by 0
		else:
			damage player's tool by 3

[ShaneBeee]

I can replicate this issue.

[ShaneBeee]

Fixed in 2.5-alpha2

[ShaneBeee]

Re-opening this. Closed it by accident.
This issue has been fixed in bensku's PR, but it hasn't been merged yet.
