Hi Ak2001. This is known that will be fixed in a future update.
The same issue seems to be for ancient Sloth at level 15. His picture in album changed but not outside of it
I deleted the game and Got it through apple again. Still the same issue
Hi! I just added you as a neighbor & can report that your sloth does NOT look like a level 15 creature when I visit your farm. I am one feeding away from leveling my sloth up to 15. I will be very disappointed if this happens to me too! I already have a pyro pony that doesn't have his level-15 art!
As far as I can remember, I don't recall EVER seeing a level 15 sloth on any farm.
PLEASE address this issue TL! It is very frustrating to put all that work into leveling up a creature to 15 to find that it doesn't even change!!! And now there are two known animals this happens with!!
