The problem in my case was having my mod files as expected in C:\blahblah\Data\etc but also now having the mod in .pak form sitting in my \Documents\Larian\Divinity\Mods\ folder. When both are present, I think the Editor defaults to reading from the \Documents\ .pak file, rendering it largely read only in-editor. Try removing the .pak generated from publishing from \Documents\ and see if it helps.
Yes, that was the problem. It seems to be working fine after deleting the files from \Documents\
I'll just have to figure out how to make characters WET in a rain and after that I should be able to release a beta of my mod.
