Now I did this all myself. I was on Canti's account when all transactions/actions were made.
So I just bought two pets. I bought a duck with my account. I gave Canti, my GF, money to get a Night Stalker.
I then used 90 tickets to get 2 evolution stones for my duck(Dayman). Made it its 3rd evolution.
I gave Canti 90 tickets, through give present, for 2 evolution stones to evolve her night stalker(Nightman) to its 3rd form. I also gave her 45 more tickets to evolve her pet, Its_Just_Business.
Now the glitch! I refreshed the page on PrincessPeach and my Dayman(Duck) is now in its first form as if I never used evolution stones.
After noticing this, I went back on Canti's account to see if the same happened to Nightman(Night Stalker) and Its_Just_Business. It actually did happen! Nightman was back in his first form as if I never used stones on him, but Its_Just_Business was still in his 3rd form though.
Accounts/Pets that were affected:
PrincessPeach - Dayman (Duck)
Canti - Nightman (Night Stalker)
Anything similar happen to anyone else?
