same issue here, I climbed onto the boat from the water, got my torch out thinking that the threat of burning the boat might make him jump, he did, and swam off, then I dropped the torch, the boat burned and the quest remains active, he is long gone and the monks are just standing around repeating the same lines if I talk to them. Again can’t roll back to an earlier save as I figured I’d come back later, 20 or so hours afterwards I ended up back there and still can’t complete the mystery. It’s likely to end up the last thing left to do come the end of this week.

@sicplagu3 nope, I checked earlier and the boat is still gone, the man is nowhere to be seen and the monks are still loitering above chatting away. It’s the only “open world” thing I have left to complete now.

I fixed it in the end, look across the water to the right, there’s scaffolding. I found the guy behind the scaffolding near a wealth chest hidden in a small cave. He said his dialog, i shot him a bunch with exploding arrows, chased him around a bunch the. Swam back to the priests and they said “at last I now baptise you etc etc” and it completed. Maybe I got lucky buts that’s where I found him and if you use odins sight he still highlighted in blue. Hope that helps someone else.

@jdmedlo seems quite likely that's where he goes for everyone then, as I said in my post he was in the cave just on the other side of that bridge when I found him and that's the direction I had seen him swimming in when it first glitched. Fair enough, two of us isn't exactly 100% confirmation on how to fix it but it seems likely it will work for others too, perhaps he is supposed to head to the cave then de-spawn once the quest completes but as it's still incomplete he just hangs around indefinitely.
