I have not seen any mention of this bug being fixed in the last two patch updates.
But the current bug of losing super meter upon capturing a zone in Zone Control in Competitive is giving an undue disadvantage to teams who rightfully play the objective.
Next time you are in Comp with zone control, pay attention to how much super you lose when you are the first to cap a zone.
Every single[b] initial[/b] zone capture causes you to lose quite a chunk of super meter. Which also on the flip side gives an undue advantage to the team that captures the zone after you, because at this point it gives a proper super bonus.
TLDR; Teams that capture objectives in Comp should not lose super meter for being there first.
