The same thing happened to me, I was handling one of Reda's quests and was underleveled for that quest.Originally Posted by Lance_Taxi Go to original post
I traveled some distance away (probably restarted) and Senu was back.
No need to start another game just yet, it's not really a glitch, or at least, it wasn't for me. As someone else has said, it's the beginning of a quest. Senu heard a whistle and flew away, you have to investigate the source of the whistle. Roam around the place where you lost Senu and you'll run into a woman, an old friend of Bayek's. She lives in a cave on the island, not very far from the river, if I'm remembering correctly. Senu will be back when you've met up with her.Originally Posted by hjalteersej Go to original post
It is a quest. You have not lost Senu. If you are in a swamp area, then search for that cave. Even I freaked out, I thought Senu was really gone. I would've killed anything and everyone to get her back. But, then I found that lady and what a relief.
I still wanted to beat her up for giving me a heart attack.
