Advisors Chests desapers ???

For some reason the chests advisors are missing for the game since last week (empire store), was it removed from the game ? If so, why ???
Its an important feature because some adv dont drop in quests chests, actually quite a few dont drop, most drop only once for the player for rewards for quests, but some you have to chouse, some you may louse for some reason, the game needs to provide a way to get those advs, and it was an nice feature to expend your eps.

 

Thanks !
