Oh man, the list above wasn't the full list - I guess it was only the ones with configuration, since I took them from the side bar...
The actual one that broke it seems to be Auto Select, which, based on the issue on GitHub, is something I assume you're familiar with - so I guess I wasted your time, sorry about that! At least I'm glad to have it solved and have everything working.
On a side note, appreciate your work (and your willingness to help!)
