also sorry if I didn't meet the standards. If you really want me to fit them for this one-liner, I can surely do that!

Looks good. Could you add a test case in com.plotsquared.core.plot.PlotRangeIteratorTest to avoid regressions here? That would be very nice.

Looks good, thanks for the contribution!

Sure! When I come home I will do that

About the unit-tests:

It looks like that junit was upgraded to junit 5, but the imports haven't been updated?

Should this be handled in a different PR?

Edit:
I have written the test, and I converted the imports on my side.

[NotMyFault]

Some tests are using JUnit 4, newer ones are using JUnit 5. Targeting the newer one is preferable. But no, you can append it to this PR.

Thank you very much!
