Hmm...odd. I was looking for who approved after I delivered the ram meat and there was nothing. But there might be some other trigger at work where I needed to do something else to trigger it there. I don't know. It's so random at times,the approvals, or so it appears.
I didn't do many missions because i wanted to get Sera early on and instantly so i'd have her in my party when doing the rest of hinterlands missions and boy, the approvals from Sera were raining like mad.
Also LOL. Y'all remember this unlucky couple of mage and inquisition scout who were on a cute picnic date and were about to get it on and templars attacked? When i asked this poor scout about what happened...:
"Sera approves"
Of course you'd approve, baby gurl.
Edit: she approved of the picnic date, not the attack. Fyi.
