@Horofic it seems that your changes broke the tests. Could you fix them?

[Horofic]

Im aware the tests on pypy3.9 still fail. Not sure why this happens, but it's unrelated to the previous tests failing. Will commit a fix for this as well.

[JSCU-CNI]

Thanks for your effort @Horofic. On a side note, are you planning on running tests against pypy3.10 sometime in the future?

Yes we are! I am currently in the process of adding tests for pypy3.10 to our pipeline(s).

[Horofic]

I did some digging into this bug, but was unable to figure out what exactly goes wrong in pypy3.9. After some testing, it seems that pypy3.10 works correctly. So, in the light of moving towards pypy3.10 I will try and add some safeguard to the plocate parsing helper, untill we are fully moved.

Ill create a seperate PR where I move the *locate.py helper files into their respective plugin. As is done in #507 as well.

We seem to have found somewhat of a workaround for PyPy 3.9. I ain't pretty, but at least it works 😄
