Ok, I already downloaded new version, but I avoid to play it because I have to check all my decks and change them if some blue card is replaced by green card in mono blue deck or something like that. I hate that.
@Stassy - Yes, clicking on the graveyard means viewing the graveyard.
I know that
Elixir of Immortality is only in Limited and it has bug in old version (which I am using).
I put artifact in Constructed version by replacing card Engineered Explosive with it. It has same bug.
(Since cards can be easily imported from Limited to Constructed (vice versa), so I think that artifact has same code for both Magic version: Limited and Constructed.)
As I said before no one reported that
Elixir of Immortality has bug for older version. It is possible that bug still exists in newer version and that is the reason why I reported bug. I will try to re-produce bug in latest version and let you know or.. you could try by yourself and see if there is bug.

Detailed explanation how to reproduce the bug:
Ability of
Elixir of Immortality has to be used at least 3 or more times. At least 2 or more cards must be in Graveyard (cast some spells from your hand, too). After artifact ability is used and graveyard is shuffled into library, play new spell from your hand and view graveyard for several times (3-5). If graveyard contains cards that are already shuffled into library, bug is reproduced. After you play and use
Elixir of Immortality, your library will grow (check number of cards).
# The best deck for testing this is any kind of Re-animator deck (which does not kill opponent in first three turns) or Ensnaring bridge/Grafted skullcap deck. Just do not forget to put
Elixir of Immortality into deck.
