Elsa's you say :
- animations don't play if they aren't on your screen, major improvement to memory
Well, my dragons showing on screen are often frozen! If I hit the habitat then the dragon it may move again but not always. Also, most of the time at least 1 dragon in breeding den is invisible and often both. Sometimes if I move the den toward top of screen 1 will reappear. Seems like you have it backwards....dragons off the screen are cavorting about and those visible are frozen.
I have a 2016 Android running Oreo with 2 gig memory and with DS running I have 481mb free.
Can you explain what's happening here?
