I got a total 36 energy left, but when I use it on a case during 15 energy cost special, the energy DISAPPEARED! Leaving me only 5 energy left when I didn't even use it! Where did the 29 energy went to?! It's not just once, 2nd time, I lost another 20 energy without using it AT ALL.

Why it's that happening??
