Hello, I want to report a bug.
Catch-Up doesn’t have duplicats protection. I got 3 legendaries but only 3 which I already had but golden ones.
Before todays opening I have some more missing legendaries form previous expansions but I got 2 in standard packs.
Which Legendaries did you get? And which are you still missing?
Catch-up packs give 1 (or more) card of each of the last five expansions. But as far as I know, duplicate protection is still per expansion. So if it rolls a Titans Legendary that you have, it will reroll into another Titans Legendary that you do not have yet. If you already have all Titans Legendaries, then it will not reroll. Even if you are still missing a Festival Legendary.
I had similar things happening to me but I think I understand how it works now. So each catchup pack has five slots. Just to make things easier, assume you have enough number of cards that each slot only gives you 1 card (so 5 cards in all per catchup pack). Say you have missing legendaries from Titans, but not from Festival. If in a catchup pack the Titans slot rolls a legendary, you will get a Titans legendary that you are missing. But if the Festival slot rolls a legendary, you will only get a (duplicate) Festival legendary, even though you have missing legendaries in Titans.
