map not saving [solved]

[sdzen]

minetest version is the latest git going off the current date of the post.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

15:12:36: VERBOSE[main]: ServerMap::ServerMap(std::string, IGameDef*, EmergeManager*)
15:12:36: INFO[main]: WARNING: ServerMap: Failed to load map from /home/sdzen/.minetest/worlds/world, exception: ServerMap::loadMapMeta(): [end_of_params] not found
15:12:36: INFO[main]: Please remove the map or fix it.

15:12:36: VERBOSE[main]: scriptapi_add_environment

anyone care to explain why this suddenly appeared after an minetest update?

Try using the map_meta.txt of an backup of the world.

Try using the map_meta.txt of an backup of the world.

or a similar map_meta.txt? that seemed to do the trick! (I neglect to make backups so I suppose using the only other map thatr I didn't set to be an existencial hell with little to no water and hoards of undead demons rolling across a desolate wasteland.) thank you gents

Well, the seed is stored in map_meta.txt, so if you replace it with a different one then the map will look really strange at the borders where the mapblocks that are generated with the old seed hit the new ones.

It happened again after shutting down my computer without stopping minetestserver.

You shouldnt to this.
I guess the OS sends a kill signal to the server, then the server starts writing stuff to disk, but the OS too impatient and just force kills it without waiting until the saving is done.

Yes, My map is no longer saving either. Any help? I'm lost to why it is doing this..

[BadWolf]

This is good to know... my server crashed a couple times yesterday, at least that's the only thing that I can reason why it happened to me. At least this is only a mod testing map, before I set up my real server

i had the same problem

My post on the bug
http://forum.minetest.net/viewtopic.php?id=6311

sfan5 told me to remove the map_meta.txt file.
This seems to work every time it happens to me (the "map_meta.txt file" is found in your world file

hope this helps
