All sheep became white after updating

When I logged on after updating to version 1.0.8, all of my dyed sheep and natural sheep that were black, brown and grey turned white. I reported this bug as MCPE 21748 but it was closed as a duplicate even though the bug itself does not seem to be resolved. When I sheer the sheep, they are dropping their original color wool for both the dyed colors and the natural non-white colors. This bug occurs in creative and survival worlds since the 1.0.8 update both local, single player games and multiplayer realms. Attempting to dye the sheep back to the color of wool they drop is unsuccessful. It would be preferable for sheep to visibly remain the color of wool they are dropping so we know which sheep to sheer. Moderators, do you know if our colored sheep that turned white will revert to their true color of the wool they are dropping when the bug is fixed, or should we kill them and start over dying new sheep once the bug is fixed?
