We found a fix! For those with Windows that have no-map, here's a link to do a manual fix.
I will be working on a new windows installer which will do this for you. Stay tuned! (Update… the installer inclusion is proving improbable at present.. we’re sticking with the workaround for now)

SPECIAL THANKS to the discord folks.. namely Chokepoint, RightHandMan, MB, and JaySheepdog.. really appreciate your efforts and research! So grateful.
Cheers, G
Thank you! This fixed it!
