So I was playing through Chapter 3 of FE4, and I just seized Madino. Thing is that the chapter doesn't progress after this point. I'm playing on the latest Project Naga patch too, and I already beat the game once, so I have no idea why this happened on my 2nd run. At least Deirdre is safe and Eldigan doesn't go and get himself killed. Maybe this is the secret true ending lol
