I’m having a similar bug at the risen giants, they do their stuff and attack but i cant interact with or use the cannons to fight back. Managed to eventually kill them using class based reflects but after that i couldn’t interact with the helicopter so cant progress further.
Same here, the giants start doing their stuff but i cannot interact with the cannons at all.
Tried multiple times, staying inside the ship or outside until that part triggers makes no difference, it bugs either way.
Going back inside the ship and attempting to use the anvil…also not working.
