It sounded as if this bug had been fixed for 1.3, but when the final blow that finishes off an opponent is struck with the Vampire Dagger I don't receive the additional HP before the match ends. Frequently, this means that I don't get an EM, even if the +6 to my HP should get me back to 100. This has happened numerous times against Level 3 (Elder) opponents, but I am not sure if it happens in PVP, the Arena, etc.
