Bugs in ACB! (Assassin's Creed: Brotherhood)

guys help pzh, I have such a bug when I kill enemies they still shine like they are alive

I don't know if it's too late, but. Can you please tell me, I ran into an unpleasant bug, I stopped showing throwing knives on Ezio's belt on the forum, that some lucky guys also caught this bug, but I did not see an answer with a solution, I ran into this bug after receiving a parachute from Lionardo , on suits (Altair, Altair's armor, Helmschmid's armor) knives on the belt are present, not only on the standard suit, when the color of the clothes changes, they appear on the belt for a second, then disappear again. Can you please tell me this bug can somehow be fixed or just need to read a new game?
Ps Visited to reinstall the game from scratch, still the bug persisted.

At the end of the additional task, hell on wheels, I continue to ride the tank endlessly. I don’t see the end of the mission, I just ride back and forth. Please help!
