I am a developer of Pyanodons. Many users use miniloaders for pY, and this is a point of contention for not updating saves to 2.0. Could you perhaps add a migration to convert miniloaders into the loaders added by your mod?
This is as ready as It's going to be. I think it is pretty complete and functional. I likely won't do any more polish here, or cover many other edge cases. However, if there is a bad bug, I'll certainly fix that if I can.
