Corrupted Worlds

[RasPiManiac]

Hello,

I have a problem where sometimes after I have exited to the OS and relaunched Luanti and then loaded the world I was playing, it only gets to "Creating Server" and then crashes. I get this error from debug.txt:

Code: Select all

2025-11-13 12:23:19: ERROR[Main]: A serialization error occurred:
2025-11-13 12:23:19: ERROR[Main]: ServerEnvironment::loadMeta(): EnvArgsEnd not found!
2025-11-13 12:23:19: ERROR[Main]: The server is probably running a different version of Luanti.

Aborted (core dumped) 

And I cannot load the world again. However, I found a solution where I paste the world.mt, and map.sqlite into a new world folder, and it works okay. I think there are some mapgen glitches though :D

If anyone can help!

the mapgen glitches are from the seed of the original world being different from the new world you pasted the map.sqlite + world.mt files into
you should paste the map_meta.txt as it has the seed
(or alternatively find the original seed by going to the corrupted world's map_meta.txt and finding a line that is just `seed = <seed>` then pasting that seed into the "seed" field in the world creator)

Thanks for the tip. I'm more interested in fixing the whole thing in the first place though.

from the error message (and a little bit of experimenting), `env_meta.txt` is corrupted
i dont know what the corrupted version looks like (probably complete binary non-sense); but replacing it should work at the cost of things like the days counter being reset

This bug is very old, from 0.4.13 times iirc.
It is sufficient to simple delete env_meta.txt. No need to create a new world etc…

Afaik you only lose the ingame time of day (and total play time in the world) by this, so nothing particularly important.

Ah thank you, I did not realize this was such an old bug since I have never had problems with it until 5.14.0

I thought it was fixed at some point. But maybe it has resurfaced now…

[AtomicCheese]

wow that old?! thats crazy that it hasnt been fixed

Nothing gets fixed whose cause isn't known, and I figure this is rare enough for that to be the case here.

Hm, maybe I should roll up my sleeves and get dirty in the engine code... :D (probably not)
