What you were expecting to happen, and what actually happened:
Played through the 3rd Forest of Thorns and did not get the x7 pets expected on Legends Reborn. I should have 13 copies and only have 8 as shown.
How often does this happen? When did it begin happening?
Happened once - today.
Steps to make it happen again
Doubt I can duplicate it but expect I’ll be short pets after completing the 4 pass of Legends Reborn where I’ll be expecting x8 copies and so on.
Looks like you upgraded the pet once already using 5 copies. Add the 5 copies to the 8 showing means you received 13 in total. Everything is all good. Have a good day.
