Dead Men Tell No Tales (SPOILERS ALL OVER)

PS4 player. Before the tournament, I spoke with BP and the herald about the dead kiddo. Then, I joined, fought, and won. I got my prize from Hanush, and immediately set off to the ambush, but guess what? No rope, no ambush… and I tried at different hours, I restarted the game, reloaded the tournament, absolutely no sign of the bugger! I gave up for now and went to have a bath with Capon.
But you wanna know what’s WEIRDEST in all this?? This is my second playthrough. In my first one, it worked as intended, he was there, I killed him, happy times. So what the hell is wrong here?
