Ship Upgrade Material Never Get Filled

Issue description

Game version and build number

Attachments

I notice the odd amount of iron delivered. Check that there is a supply of iron accessible on your island- or trade for it if you need to. If there isn't enough, this is indeed what will happen.

Check the storages, you probably have forbidden the export of iron.
