BUG - Legendary Node - Bone Breaker

The Bone Breaker Legendary Node state “Every 12 seconds, your next Skill is guaranteed to Overpower”, however, as with similar nodes where there’s a count-down/up so you know when it’s about to trigger, I do not see a 12 second timer counting up/down to indicate next skill will overpower. Please can you confirm if this Legendary Node is actually working at all?

Same problem here. The overpower indicator and damage were working earlier today. Then I rearranged some glyphs and nodes. Now, the indicator never shows up and there is no overpower happening.
