Assassin's Creed Unity

If anyone has encountered the problem of not receiving the trophy, I will describe the method of obtaining it and possibly avoiding the glitches.
1) Complete the game despite the glitch - it will take a maximum of 2.5 hours to open this trophy.
2) After everything is completed and one trophy is missing, delete everything related to this game (the game itself and all saves). Reinstall and start over.
3) To get the trophy faster, go through the city mission, in the lower right corner - “Theft of the Tapestry”, where you give 37,500 monetary units, which is easily enough for leveling up. The main thing is to throw smoke bombs and think, but the mission is simple, if you beat the game, you can even beat it “naked” Arno.
4) So, we have money, we go to the theater, we didn’t even go near it before. You are introduced to the cafe, then you take money from the chest and then we start pumping: The main thing is not to touch ANYTHING at the time of purchase, that is, buy, wait until the game loads everything and make sure that the menu is functioning normally - buy the next upgrade. After you have purchased and the download has completed, exit the leveling menu and the trophy will be given immediately if everything was done correctly. Thanks for the tips below, BUT there, this way and that, in order you can only upgrade the building.
And the most important thing is that I didn’t go through madam’s missions, I didn’t let them play the game like last time, under the general game, through the chat. I honestly don’t know what could have caused the glitch.
