Summon loses track when it shouldn't

[AdamH]

Game 110640379, my turn 7.

I summon a Blessed Village, revealing The Moon's Gift, I choose to take The Moon's Gift now. I select a card from my discard other than the Blessed Village I just gained to the top of my deck. Now, the game log says "Summon can no longer move Blessed Village (it already moved)). The Blessed Village was still in the same place it was before I took The Moon's Gift -- right on top of my discard pile. Why did Summon lose track of it? I searched for a ruling about this but I couldn't find anything, this has to be a bug, right?

I think you are right. I guess the game treats looking through the discard as "changing" the discard pile, because sometimes it may not be able to decide if you took the top card or another copy. But that seems to be not relevant here. I'll ask about this. Thanks for pointing it out.
