Testing build fixes this issue!
I've tried a dfhack reinstall, maybe its just me? Is there any kind of log file I can throw here?
Mm currently isn't loading default modlists, and doesnt load modlists when a manual load is attempted.
I'm not getting any kind of error, it just seems to not be working at all.
Deleting, saving, renaming and setting as default all seem to work.
