Assassinate, Amplify Damage, Track, Strygywr's Thirst...?

I'm Bounty Hunter viewing the replay from my perspective. I should have sight of that tracked guy who's running through some trees, and I know that I did, and the track buff is even visible above his head -- but the replay says otherwise, that I don't have sight, that I don't have vision.

This error applies to all shared vision abilities.
