I just 100% assassins creed botherhood two times

The ezio collection is bugged on Xbox (i can’t speak for PlayStation) it’s random what achievements will bug out for you if any so far I had to play 2 play throughs of ac 2 and this game. Now on to revelations I hope it doesn’t bug on me or if it does it doesn’t bug on a grindy achievement. Thank you Ubisoft for this masterpiece of a collection… And I just wanna say on my second play through I just finished I thought it bugged again i was about to die, I quit the game and went back in thankfully the achievement popped with a massive delay thank you xbox.
