Thanks for the PR @iridiium - looks like docstring validation is failing here and needs fixed. I am aware of and currently fixing the issues, sorry for requesting reviews when unneeded. @iridiium we changed how we specify the pending errors in `code_checks.sh` and you'll have to resolve the conflicts now, sorry about it. @iridiium if you want I can help with the updating of the error exceptions in the shell script. Just let me know > @iridiium if you want I can help with the updating of the error exceptions in the shell script. Just let me know

~~Sorry, I've been a bit busy lately, although I will try and work on this soon. I haven't been following the changes much and am not too sure on how to update this, how would I do so?~~

I haven't changed much, so I'd rather start fresh
