Versions:

I'm using a minecraft server [1.12.2-R0.1-SNAPSHOT] (do /ver in your console) I'm using skript version [2.2-dev37c] (do /ver skript in your console) I'm using SkEmail version [1.2] (do /ver skemail in your console)

About the issue:

I got a [java|skript] error. My code is:

discord command mailtest [<text>]:
    trigger:
        make new email:
            set object of email to "test"

            set body of email to "~"

            set receiver of email to "%arg-1%"
        send last email 

and my error is:

[10:24:57 ERROR]: #!#!
[10:24:57 ERROR]: #!#! [Skript] Severe Error:
[10:24:57 ERROR]: #!#!
[10:24:57 ERROR]: #!#! Something went horribly wrong with Skript.
[10:24:57 ERROR]: #!#! This issue is NOT your fault! You probably can't fix it yourself, either.
[10:24:57 ERROR]: #!#! It looks like you are using some plugin(s) that alter how Skript works (addons).
[10:24:57 ERROR]: #!#! Following plugins are probably related to this error in some way:
[10:24:57 ERROR]: #!#! Vixio (http://vixio.space)
[10:24:57 ERROR]: #!#! You should try disabling those plugins one by one, trying to find which one causes it.
[10:24:57 ERROR]: #!#! If the error doesn't disappear even after disabling all listed plugins, it is probably Skript issue.
[10:24:57 ERROR]: #!#! In that case, you will be given instruction on how should you report it.
[10:24:57 ERROR]: #!#! On the other hand, if the error disappears when disabling some plugin, report it to author of that plugin.
[10:24:57 ERROR]: #!#! Only if the author tells you to do so, report it as Skript issue (url below)
[10:24:57 ERROR]: #!#! Issue tracker: https://github.com/SkriptLang/Skript/issues (only if you know what you're doing!)
