ATT currently lists the coordinates for Berrel as 62.0 and 42.8, these are incorrect and the correct ones are 60.6, 39.8 (next to the meeting stone for The Nokhud Offensive)

This appears to be correct in ATT now. Was fixed in e736ab9#diff-1cdc3268c7547afe324f7974ce91ebd5995d9bd28a0073628cdff97a15460185L352.
