i am playing survival minecraft pocket edition 1.14.60 on my iphone xr (it is version 13.4.1). i have gotten to the ended dragon and have spent a long time preparing for this moment. however, every time i die and come back to the end, the ended dragon has all its health back! i have made sure multiple times that the end crystals have been eradicated yet still it's health keeps coming back. i am very frustrated because i really would like to beat it but it seems impossible.
