I just mixed my grandmaster expic pet with my adult sea dragon and the results are beyond explanation. I just recieved an egg that has talents on it all the way from uncommon to epic even though neither of my original pets had a single uncommon talent upon them. I view that as being odd as the egg has one, two, three, and four dot ranked potential talents, so where did the one dot talents come from?
Okay, I might chalk all of this up to a display issue, but something else occurred as well. My grandmaster pet looks the same as always but now my sea dragon that had five potential epic talents upon it has somehow changed to having six potential expic talents. Since when does mixing two pets together to create an egg change the non-manifested potential talents on the adult pets?
We don't know the details of the display bug. What we do know is that unmanifested slots display incorrectly. And we also know that the manifested slots will display correctly once the slots manifest.
The display of the unmanifested slots doesn't really matter much. Incorrect is incorrect. What's most important is that the manifested slots display correctly. A manifested slot changing or displaying incorrectly would be a new concern.
