Hi
In Unity4.6.5 upper, I faced the bug.
Image disappears when some buttons are clicked.
Only on iOS or Android devices.
In Unity 4.6.3, It was not occured.
But Apple request 64-bit binary, so I can’t use it.
Give Me Solution for this bug…
OK I found a solution.
Remove packing tag from sprites which are disappeard . Then they are displayed always.
