not sure this is a bug as such.......or merely an oversight.......but not being able to use a bandage until after you have received one loss means that they are useless if you go into an island with your last 5 energy.......since if you lose a battle, you dont have the option to use one, it just kicks you out

Thanks for reporting. You're right, this is a kind of oversight. We made an update to deal with it: pets still require 5 energy to enter portal but at least 1 energy will always remain when the pet passes through portal.

Thanks, that's great news :)
