So, if you don't claim the 1st reward as soon as it pops up after you've earned 15 stamps, do you lose all those collected after in the mean time? I think that may be the case so wanted to post for awareness if that's true.
I did the x-men arcade 8 times on legendary. 3 stamps x 8 runs =24 stamps earned for week 1.
1st milestone is 15 stamps (=5 runs). 24 - 15 = 9 stamps remaining (3 stamps x 3 runs = 9 stamps).
Next milestone is also 15 so 15 - 9 = 6 stamps remaining, or so it should be, right?
However, mine shows that there are 9 stamps still needed and I think 3 just disappeared into thin air because I did not claim the milestone as soon as I hit 15, but waited until the next run was completed before realizing a milestone had been reached to claim the first reward.
If that's the case, that really sucks and beware.
