Expand.save

Reproduction steps

I just saved the game as normal.
Wanted to continue today and am slapped with above error messages in a window for every save game i tried to load.
Vanilla map saves still work though.
I still hope there is a solution to this and you won't just not look at it at all just because the map was a mod.

Game version and build number

v0.7.8 b481

Operating system

Windows

Files not imported: Expand.save

It seems that map is relying on materials from mods that are not present. Is that possible?

Hello,
thanks for contacting me. No, actually the only thing i ever added to the
game was a customized map. The All-in-One Update 3.
The only thing i could imagine is that something was changed with a patch.
Otherwise there were no changes whatsoever to the
game files.

Anyway, i hope you can get something out of it to avoid future problems.
Would still be nice to continue that save file.

Thanks for your time.
