The issues that I'm having with the nightly build is that some scripts with the nightly build aren't working at all, is that supposed to happen?

If you're saying some scripts built against nightly builds aren't working (for missing methods or something like that), blame the script authors. I never guarantee that nightly updates won't do breaking changes to anything of the API that aren't available in any stable versions (and crosire never did). The readme says the same thing.

Thisscript for example works perfectly fine if I was to use SHVDN 3.6.0, but if I was to use SHVDN nightly it doesn't work at all.

Thank you! that did it, the script is now working, I did read that but didn't pay attention to it thinking it was for developers, my apologies.

And one last question, adding the ".2" should be done for every single .cs script that I'm using correct?

Yes, adding the ".2" should be fine for most .cs scripts. I'm not aware of any scripts that are supposed to run under the v3 API but the.3 is missing (making them being able to run in nightly versions without renaming). My apologies for not logging warnings for missing version notations to both the log file and the console, too.
