Production Boosts too short

Production Boosts for watching videos are not as long as they should be. It felt like I was doing them too often, but just now u had boosted taverns around noon and they lost their boost before 5:30.  It’s supposed to be a 10 hour boost. 

Seems like blacksmith and food are short too but I can attest to the taverns today. 

I have boost them and its 8 hours for Blacksmith

10 hours for taverns :

I test it and 4 hours 22 min later my timer is correct :
