In our clocks we have 2 advert breaks per hour:
advert manger should only schedule in those gaps.......
This week we have a special promo which we have manually dropped into the log......
it's cart type was an advert, when I scheduled this weeks adverts, an ad break appeared at half past each hour!
ad manager thinks this new promo is an ad break.
I have removed the promo, changed its type and rescheduled, all is now fine.
but its a bug !
