Dropped a Gunner near the Legendary Fort. The Gunner: Started shooting whilst still on his boat, then *continued rowing* after destroying the building. Has his bullets come from mysterious directions. Two replays attached but it seems to almost randomise every time I re-launch the game. (Watch in HD to see the bullets and muzzle flash) This may also be a potential vector for replay divergence but I am yet to fully investigate that.
Here's another one, different base, same behaviours - shooting whilst rowing and bullets coming from a random location.
