Game crashes every time I'm on the Pirate's Life tale 2

Hello fellow pirates, so here is my problem, I tryed to finish the tall tale 2, the one of the sirens, and every time I'm near the citadel, game crashes, not on any specific part, but I've tryed to compelte the tale like 5 times and it crashed 5 times on diferent parts of the mission. Any idea why this can be? My graphics card is an AMD radeon.
Thank you guys!
