if you finished the Lizard's Curse and Lizard's Treasure quests now you just gotta go to your house to get the crow to show up. I slept untill morning but noticed other people got it randomly by leaving and re-entering their huts. Try those methods out and see. If it still doesn't work something has gone awry. Worst case scenario you'll have to download the previous update to kick off the scene like I had to with Logan's werewolf dungeon side quest
Sorry if I worded things weirdly, but yes you had to progress the Lizard's Treasure quest to get that scene at all. The Orc's War is only needed if for whatever reason the scene wasn't triggering since Nameless shows up in that quest as well for a brief period if you camp with Groth. Sorry if I caused any problems. Triggering the scene can be a bit finicky depending on the update version
