Upgraded Shards Revert?

[Bigglesbee]

Hey guys,

I'm new here and searched the forums but couldn't seem to find an answer. I upgraded a shard to a Shard of Gratitude, played with it for a few matches, then suddenly the next match I notice it reverted back to the unupgraded version.

Is this a thing that happens? What gives?

Thanks .

Were you playing in PvP1? All cards get reverted to the unupgraded form there.

Oh you know what? I think I was. Lol, thanks for the tip.
