Assassin's Creed Unity

At the time of writing this tip (03/14/2016) with game version 1.05, the “Complete all Part N Memories” trophies are still glitchy. I didn't get a trophy for part 12. I had to replay the entire game again, because after replaying both the last mission and the entire 12th part, they did not give me the trophy. There were no saves.
Be careful and dump your saves onto the flash drive after each part, or at least after several parts. The game, of course, goes by quickly, but it’s still better not to waste time a second time.

This achievement is buggy and may not work the first time. They gave me the achievement after 4 hours. At the same time, I did not replay, but continued to play.
