Hi, I have an error with the version 2.5.1 on loading the save game. It crashes while loading. Although it is a highly modded run. the error still occurs if the other mods are disabled and just Factorissimo2 is running. With the version 2.4.6 the world is loading like intended.
A screenshot of the error log, the additional mods and the save file are in the Dropbox.

I just noticed I fucked up the title, my apologies for that.

One of your factory buildings was built by a force that no longer exists. Recreate a force with the exact same name as the missing force in the editor and you should be good to go.

Wait up, you can't edit forces if you can't load the save. Hmm.

Okay, I've published an update that should fix this issue. Thanks for the report!

Thank you very very much. Correct me If I'm wrong, but I could have loaded the save file with a version which works and edit the force, couldn't I?

That would have worked too, but it's better to have a fix for those people who would run into this issue and not ask.

Yeah that's true, have a nice day.
