[confirmed]Flowstone Sculpture abilities don't survive copy

[Korath]

Describe the bug:
Flowstone Sculpture loses the abilities it gained from its activated ability if it becomes a copy of something else. (Cytoshape's the easiest way to test.)

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Today's dev build, ae31685.

What exactly should be the correct behavior/interaction?
Copying doesn't add or remove abilities except those granted directly from either a card's rules text (or a very few other things that aren't relevant here; see rule 706.2 for the gory details). If something gives a card flying or first strike or trample or whatever, that doesn't get copied from or copied over.

Are any other cards possibly affected by this bug?
Only as an artifact of how it stores its added abilities. Making a Shapeshifter copy a Flowstone Sculpture, or making a previously-activated Flowstone Sculpture copy a Shapeshifter, is a pretty neat party trick, for example.
