Licensing Question

[Qwarkk]

So I have been working on a KoS script for years. I wrote it for my own personal use but would now like to release it for others to enjoy. I have never released anything before and so I have suddenly become aware of licensing.

I have looked around at the various license options and I will admit I don't fully understand it. I want people to be able to use it freely and do what ever they want to it/with it. The one thing I want to ensure is that if they redistribute this work, they do so under the same license I choose. As i understand it (please correct me if this is wrong) this will prevent someone altering the work and redistributing it under a much more restrictive license (which could be done with a MIT license i think?). I want this to be as available as possible across any version in the future.

With this in mind I settled on the CC-BY-SA-4.0 License (but I have no idea if this is a good choice). 

Where It gets difficult is that the KoS script uses libraries from the KSLib collection. I took the lib_navball and simply removed the ones I didn't need (EDIT: and i have also added some comments to explain to potential users of my script how the functions in lib_navball work / why they are used).  This is licensed under MIT. Am i right in thinking that as long as I distribute the file with its copyright info / license info then I am safe to redistribute it? The top of the file looks like this:

Quote

// lib_navball.ks - A library of functions to calculate navball-based directions.
// Copyright © 2015,2017,2019 KSLib team
// Lic. MIT

Is it an issue that I am releasing the work under one license containing other work under another license?

Furthermore, I relied on help from the amzing KoS community when i hit roadblocks writing the script. I have functions included which I have taken from the KoS subreddit.  The functions were written by other people to solve problems posted in the subreddit (but not by me - their solutions just happened to suited my needs). Am i safe to redistribute this work? I intend to give credit of course.

Thank you for any help

To answer the question, MIT licensed content can be redistributed under a more restrictive license (and sublicensed), as long as you include the copyright notice.

However, why not just distribute the whole thing under MIT?
