Just wanted to give everyone a heads up on the Battle Crate item issue.
Like a lot of people I reached 49 and still had items locked from the Battle Crates. I stated a new character and found that leveling through the Crate levels did indeed unlock the rewards I was missing EXCEPT the Nightmare knife.
Battle Crates with the new character are now rewarding nothing, but the knife is still locked. I remember there being something around the update changing the knife or something, hopefully Ubisoft will actually fix this mess, but if you're missing items other than that I can confirm that starting a new character works.
Hopefully this helps someone![]()
