I failed to save the replay but in a SP game where is was Oak,
i used a shield to save Oculus from sudden death. Although i activated it,
it did not show Oculus as shielded ( the white/gray cover ).

First i thought that i missed and shielded a minion but it happen again.
This time it was just me, Oculus and an enemy and yet no shield visible.

Can't say if the shield was in effect but it aleast didn't show up.
