Thanks for the contribution!! 💯

However I don't think this PR can or should close #309: it does not add the remaining errors.

[sladyn98]

@TheSven73 Yes, I am adding the remaining in a second commit :)

[TheSven73]

That's cool, but why not add both commits to the same PR? Or is that the plan?

Approved CI to run -- thanks for joining the project! :)

@TheSven73 Yes, I am adding the remaining in a second commit :)

To clarify: the problem is that the PR closes automatically the issue if you write "Closes #309" :)

So either remove that comment (so that the issue is not automatically closed) or add the other commit here.

Also please fix the issues that @ksquirrel found.
