[Update 8/31]: This issue has now been fixed with the release of Ver.20.1.2 for Android.
We have noticed select ★7 rarity and higher monsters are mistakenly dispensed with the wrong egg visuals from Egg Machines on Android devices.
Affected Monster Types:
Evo Material
Awaken Material
Enhance Material
Redeemable Material
This is a display issue and will not affect the monsters that are obtained through the Egg Machine.
Additionally, this issue will not occur after the monster is obtained for the second time onwards.
We will be addressing this issue in a future update.
We apologize for any confusion this may have caused and thank you for enjoying Puzzle & Dragons.
