Longest fail streak on stars

[Legolas Bow of Athena]

Is that 14 in a row in one sitting?

Or do you buy 3 medals, then try. wait some time. buy 3 then try, etc?

I buy a medal every time i see one at the fair and every lab chance to buy a star I do. Basically once or twice a day over 2 weeks.

Basically just ready to give up on the game at this point, spend all day grinding and watching arena hoping for gems. Finally get enough for 3 medals then fail. 4 or 5 times to fail sure I could see that, but 14 times and a row and counting.... It's just mentally taxing.
