Snipers objective on Catacombs level broken

[Darthtaters8]

In the Catacombs level I shot all the snipers I could see but it didn't complete the objective, I looked at all the walls and didn't see any snipers and no one was shooting at me. I'm sure this is a bug plz fix

It's not bugged, I completed that objective many times. You just missed one, at least.
To give you a hint, at the very beginning of the level before you enter the castle, you can snipe 4 of them.
