"Map missing" issue?

[rugged jay]

hi, so the other day I played the game, got off and decided to play tonight, only to realise I can't load my saves, any of them, because a "map is missing" and specifically "Louisville, KY" is missing under maps... is it a mod problem? is it a glitch? and most importantly is it fixable? I'm very confused and have no idea what to make of the problem so if I could have any support I'd be very grateful

oh and another strange thing, this doesn't seem to be a problem for new saves

[pseudo stag]

There was a new update yesterday, could be because of that. Is it a particularly old save? Do you have any older saves without mods?

[rugged jay]

hi!! this was on an older version of B41, could that still be affected by a new update? and nope, all of my saves (except one which I think was me playing the tutorial where it was too early for me to be using mods anyway) have mods of some kind

[pseudo stag]

Hm, that would be unusual. Can you compress the save folder and send it to me so I can see if it can be fixed?

It may be possible to just replace the map info from another save, which would allow the save to load

[rugged jay]

absolutely! forgive my ignorance but how do I do this?

[pseudo stag]

Go to %UserProfile%\Zomboid\Saves on your PC and find the specific save folder there, it will be the same name as your save

Then Right Click > Compress > ZIP

And send that zip

[rugged jay]

is it one of these options? I've played a bit with the files before (making extra copies for situations like this) but I've never heard of a compress option before

[pseudo stag]

The option you have highlighted will work fine

I was referring to this option in Windows 11

[rugged jay]

ah well don't use Windows 11 but whatever works works

I'll try it and get back to you

[rugged jay]

I used the highlighted option and this is what I got, hope it helps ❤️

[pseudo stag]

I think I may have found a fix. Try creating a new save with the exact same mods, especially map mods

Then go to its save folder and copy the map_ver.bin file from it and paste it into this broken save

After that you should be able to load it

[rugged jay]

and replace the existing file I'm guessing

it worked

well, at least, I can go onto the server, I'll just make sure it's working

yep!!! it worked

thanks so much for the help, but if it's alright can I ask what you think caused the problem, and is there anyway I can avoid it in the future?

[pseudo stag]

I can only guess its some sort of mod modification, then the mod updated, which caused the problem
