I installed your mod and I loaded my normal map not thinking it would alter anything, but it has put the maze everywhere and i cant get rid of it, I tried uninstalling mod and still nothing. all my autosaves have it also. Please help me remove it. I have over 200 hours in the save :(

Just wondering, why did you think it wouldn't alter the game heavily? It's a "big mod" and looks like a maze?

It will change new chunks on maze generation, removing resources, water, etc. But existing chunks will be fine unless regenerated for some reason.

Without modding/console commands the best you can do is landfill the green water that remains after the mod is uninstalled.

I highly recommend taking an offline backup of any save you value. Especially if you are running 0.17 because it is experimental. I do so almost daily.

It just surpassed my mind, and i thought it would only affect a new map, Oh well. Looks like my map is fkd. what a waste, Black area on map is unpassable

If you know how to use the command line, you can delete any chunks that you wish to regenerate. Make sure you keep a copy of the save in case you delete the wrong chunks.

You will need to adapt it to delete only the chunks you want regenerating

Thanks for your help, This looks a bit far out of my reach. Would you consider editing it for me :P,hmmm you would need all the mods etc. damnnnn this sucks

Or at least a demo on how to use it might work better for you ?

Hey thanks for the tip, I managed to download a mod that deleted the chunks for me. And it is all fixed with a bit of landfill. Cheers mate.

Great!

What's the name of the mod? In case other players want to do the same in future...

Its called Delete Empty Chunks https://mods.factorio.com/mod/DeleteEmptyChunks/discussion/5a5f1b0dadcc441024d77364

Thanks again

Nice, really glad you recovered your game
