Well, not all of them but both the two colonies I was working on at the moment. It seems that Silva's UCP mod got yanked without warning and as it was enabled in both my colonies I got the mod removed warning, but not even the very early saves could be loaded. From comments on the Steam workshop forum it looks like Silva didn't know until hearing about it there. Do you guys really not let modders know when their work is being pulled so as to give them a chance to fix whatever the issue is? And Silva's had content published as DLC. Could you guys just talk to Silva and sort this out?
