[fixed] Gift of Immortality behaves strangely

[Torque]

Describe the Bug:
Testing Gift of Immortality can be a bit awkward, but here's the sequence I observed:
1. I play two copies of Kazandu Blademaster then attach a Skullclamp and Gift of Immortality to the second one. I pass my turn and the opponent plays Consuming Vapors prompting me to sacrifice my enchanted blademaster (screenshot 1).
2. The opponent plays another Consuming Vapors and I choose to sacrifice the same blademaster. At the end of the turn, Gift of Immortality wrongly returns to the battlefield without attaching to anything (screenshot 2).
3. I play another Kazandu Blademaster and attach Skullclamp to it, at which point a Gift of Immortality shows up in my graveyard while there is still a phantom copy on the field (screenshot 3).

Which card did behave improperly?
Gift of Immortality

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
March 2021 - Allegiances and Alliances, duel

What exactly should be the correct behavior/interaction?
Gift of Immortality should not return to the field if the previously-enchanted creature is no longer on the battlefield.

Are any other cards possibly affected by this bug?
-

My apologies for the lack of a save file. I'm not sure why the function doesn't work for me. It simply doesn't generate a file.

Still behaves strangely but now differently.
Previous bug has been fixed and seems to work correctly, now. However it demonstrates an issue we have met 2,3 times in the past and I don't think we have fixed one of those, yet ( 1 of those with Animate Dead and such auras ).
If Gift of Immortality returns from graveyard and attaches to creature and then you assign the creature as an attacker or blocker it will not show on the battle window it will be still blocking or attacking correctly.

However, we have that link for that so I will close this as fixed.
