[Bug Report] Eval command not working

Bug Description

The eval command is not working, even though I have the setting enabled in the config file. It throws me an error in the console with every argument I pass to the command.

Here is the error:

java.lang.NullPointerException: Cannot invoke "javax.script.ScriptEngine.put(String, Object)" because "se" is null
