ok So here's what i tried. I re-acquired drizzle 16, and 17.
Myst V imports work just fine. My MOUL files do not work in Any of them 16/17/18b.
So clearly the issue is with my PC. Just can't figure out what it is now.
I know it was successful once. i went and looked in my uru-drizzle folder and i DO have the files there.
Began playing, and played just fine. Complete SHOCK to me!
So i guess i dont have to mess with it....
very weird....
