Safeguard on gem usage in Provision house/barracks

So i just clicked that little blue button that we all know we hardly ever use, namely the one letting you finish a stack of buffs immediately instead of waiting. I wanted to cancel the second stack in my provision house, but me being all sleepy, i clicked on the gem one instead. This gave me 25 baskets, of which i have about 1000 in my star menu. Completely not necessary for me to have them finished straight away. And, this little tiny mistake cost me 160 gems! So thats around 3.5 weeks of saving up gems, since I do not want to buy any more gems after the rollback. So I would like to suggest there be a extra pop-up asking if you want the stack to be finished straight away, to save us spending unnecessary gems. Even if i wouldve bought gems this would be a waste.
