Well, you can always put food in the region before letting it go rogue to fix that part. That's basically what we did with Grehk. The point of letting it go rogue is that you don't need to tie down any forces to the region to repair it, which can take a while sometimes.
As for Courts at 1% loyalty, I've never seen it, but I usually don't try to do that at such low values. I wouldn't know, but I've had my courts disrupted at low loyalty (15%-20%) which just undid any progress in it so far.
