I am having a problem in sequence 2, in the mission A faithful acolyte.When we dismount from the canoe that the alligator should attack me, nothing happens and even if I get closer I cannot attack it which I need to kill it to be able to complete the objective that I need. is to kill the followers in 3 minutes. which is the only thing I need to get the trophy (Complete all Mission Constraints) for platinum.

Please below video so you can see what happens to me. as I would not want to start a new game to have to complete the story again 100% to get this trophy.

if anyone knows how to fix this please let me know.

Thank u.
