I upgraded to level 10 on Thursday. I have 6 gold coins total. I don't remember if I had 5 or 6 when I upgraded. Either way, I don't see a swirlicorn in my future. (Refuse to spend gems, This game has stolen hundreds of mine).
I also am frustrated that S8 has proven, once again, that they do know how to program a use confirmation button.
On a positive note: the alicorn and naga have each shown up twice in the baron's game!
