Iron and Copper Not Visible for Export in Contracts List

Issue description

Even though I have a settlement that accepts trade in iron and copper, they are not showing up in the contracts list as options.

Reproduction steps

The error is there all the time

Game version and build number

v0.7.6 b458

Operating system

Windows

You should attach a save file.

Cant upload a save file

Pack it in a zip archive.

I’ve tried, but I receive this message every time. Is there a size limit? My file is 30 MB.

Link to Dropbox, Google Drive, OneDrive, etc.

I'm sorry, but unfortunately, without a save file, we can't do much. I took a look at the fresh game and I see the contracts there. If you have more specific repro steps, please file a new issue. Thanks!
