6stared Umbral Enchantress the last days and started using her in dragon 20.

Happened aproximately 6 out of 11 times .

Please help :) thanks

Never had this problem besides the last days using her.

Other factors(if it matters):

Team: sir niclas, madam seris, teela goremane, venus + umbral enchantress.

 I Think it always happens during the waves 1 or 2. 

Its geting hard using her, when there is a good chance of losing the energy.

edit: sadly not device related, also happens on my other smartphone

edit: seems fixed
