Lost save in AC II.

Title. I’ve been playing on the Xbox 360, as I’ve found out this is a common problem. I will be backing up by saves from now on. I had just finished sequence nine, I had all six seals, and most of the metal armor. If anyone has a save game I could pop into horizon that’s close to where I was I would greatly appreciate it. I don’t mind getting the armor and seals back if I have to. I really don’t want to do all that again, and I can’t find any on the internet.
