Secret or Glitch?

[Darkest Spectre]

Hey all, I could not find a topic on this, but while visiting our favorite fortune teller I found a spot on the edge of her pond that shows something strange. In a different area from where to toss in a coin and can see all of the other coins on the ground, there is a prompt that designates "Missing Coin" without any interaction available. I could only find it in one place and couldn't figure out anything to do with it. I don't know if it's a secret, a glitch, or something I can come back to after a later area in the game. Anyone else see this? 

My screenshot is too big to attach here and I didn't feel like messing with it to get it down to 1 MB. So I put it here in a similar Reddit: blob:https://www.reddit.com/aada1ea5-619c-45e9-9175-f7605017bdcf

Same for me, I am on my second round, when I passed by that place in my first round, I remember that was odd. But at the same time, my tought at the moment was that probably was just a detail to show you the missing coin of the person sitting at the gate entrance...
