I'm not sure what to do about it and my son has spent countless hours building in this world so I would like to save restore it.
So far I've tried:
1. setting the map_meta.txt file to 777 perms (no joy)
2. removing the file (no joy)
3. replacing with backed up older version (no joy)
4. rebooting, restarting, rebooting.
5. checking folder permissions.
6.checked system available memory and hd space
It's running on ubuntu 16.10 using the minetest 0.4.14 package and a variety of mods.
Thanks for any help.2016-12-23 17:24:55: ACTION[Main]: .__ __ __
