[still bug]Breakthrough if X > n total of cards=discard all

[Aswan jaguar]

Describe the Bug:
1- I cast Breakthrough and I autotapped all mana for X and as a result X was bigger from the number of cards drawn+the ones already in hand (I had 2 cards in hand and drawn other 4 for a total of 6 but X was 7)that resulted in engine thinking for few seconds and then making me choose to discard all cards instead of keeping them all.
2- Breakthrough instead of making you select which cards to keep and then discard the rest according to it's rules text it asks/makes you choose which cards to discard which could be confusing if you don't pay attention to submenu which asks you to select which cards to discard(submenu asks you to do the way the card is coded so submenu has also to change if you decide to fix this bug).
Which card did behave improperly ?
Breakthrough

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2016/01/15: Battle For Zendikar v2,duel

What exactly should be the correct behavior/interaction ?
1- Breakthrough if X goes bigger than the cards that you will have in hand after you draw doesn't make you discard them all.
2- Breakthrough makes you choose which X cards to keep and then ask you the order to discard the rest if any.

Are any other cards possibly affected by this bug ?

Also would be nice if the discard/keep box listed X.

Only 1 bug is still there. It doesn't let you choose the discard order. Although it would be great for choose order effects if we had an option 1 more button in menu "Don't choose order" if you select it or choose order otherwise.
