My many problems
Forli, Observation point most upper left, I can't go in range of the observation point the game freeze.
SPOILER during the dream with Altair at the end, the game froze
Venise, Mission to free thiefs in cage (3 cages), The game always freeze during this mission so I can't complete the game.
Venise, running or assassinate peoples.
During loading (loading at infinite)
I've reinstalled the game, changed my copy of the game, cleaned my PS3 with aircan, both cd and blueray disk used for cleaning lens. AND YES ALL MY OTHERS GAME WORKS FINE.
I hope those are concrete stuff for you and you read messages.
