I am running on the latest 1.10 update and after playing for a few days under crafting I have a few craft show as undefined and can't upgrade any crafts. I can't find a solution anywhere that doesn't involve restarting the story. Any ideas will be helpful.
You should uninstall/reinstall Uplay and FC4 as well as make sure your drivers are updated. If that doesn't work I recommend submitting a ticket with support.ubi.com or following the links in my signature. Let us know if this helps.
