Bug on ending Troy fight

After ending Troy fight, and after the cutscene i fell off the map. Don’t know if this is common, on my first Troy fight this didnt happen, but on my second fight with Troy i fell.
I think i was almost in the middle of the fight area, when i ended the fight.

(I’m new to this Forum, if im posting on the wrong Forum please tell me )

Happened to me every time I’ve fought him(3 times). Lose all the loot besides what the box takes.
