I remember in Kingdom Rush 1 there was a button to copy your local save to your online account, which was very helpful as I didn't have an account until late into my KR journey. I'm playing the second one now and realized that you need to be playing on an online account in order to unlock certain heroes, so I thought I'd just copy my account over.. but I can't.
Am I not seeing an option that I should be seeing or did the makers just not add this feature into the second game?
