0.17.1.1 Testers Patch Notes

There aren't many gameplay changes, but this work touched a lot of systems across the game, so I want to make sure that this all still works correctly before pushing it to main.

For modders: The mod tools are forwards compatible, so the mod tools will stay on 2020.3.30f1 for the time being.
