hi, my savegame world is corrupted when i try to open it its show me this "badzipfile" i was not able to save ...
how its happened ... i was playing then my laptop suddenly shut down .. opened laptop .. then i went for the game and its works as normal after few minutes playing
i left my main save before i leave tried to save game but its showed me as i remember "cant save ... bad zip file or smth like that" then i tried to save more worlds to avoid losing it but for the all save its showed me that "bad zip file" so i left my main world after that .... then after somehours i come back to factorio ... my main save when i try to open its says as the pic below .. so is there any way to fix it .......
game version 1.1.57

i love this game so much alots of hours playing ...
sorry im not good at english but thats my best, thank u <3

Unfortunately there is not much that can be done with this zip file. It is corrupted. I was able to recover level.dat33 up to level.dat73 but there are parts from dat0 to dat32 missing and any gap will make this save file not recoverable.

oh :/ sad
.. i have a save from same world <the corrupted world> that was 2 - 3 weeks ago from the corrupted world its was <backup> its from level.dat0 to level.dat50
and its work <but its an old save> so can it be merged with the corrupted world to restore the level dat missing ?

here is the old save

Merging of level data chunks from different save files is not allowed, it will not give anything usable.
