Weird energy Error

After we had downloaded the update my guild went to do a GvG , during that GvG i suffered from a weird problem that i hope is just a one time thing.

I was on Ele runner, I had around 50 energy and i tried to use Heal Party, at which the game gave me the message , not enough energy and didn't let me cast it, this happened a few times,it happend with Heal Party and also with holy Veil, these are the 2 i remember trying to use and getting the error.

I tried replicating the bug in a scrimmage after we were done with that much in a scrim , but with no luck,I will see if it happens in the next GvG and take some screens, don't know what else i can provide to help, if this is indeed a bug.

Thank you for your time, Xenex.

It might've just been a one time thing, since you had just downloaded a patchI
