I fear I ran into a potential glitch with the game. I went from 29->50 seashells and went the the mansion and claimed the rewards, which gives two chamber stones as rewards. The only thing, though, is that I realized later after I had stolen the 7 chambers that my count didn’t look right; I should have been at 13 chamber stones with just the 30 second raft race challenge left. I did the raft race and it brought me to 12, but I had already gotten all of the available chamber stones. I retired the fishing activity to get them but I remember getting two from there; I ended up going to Dampe’s and finding out online what each chamber stone is supposed to reward and I appear to have everything. I think that getting the two chamber stones in one batch like that at the mansion might have screwed me over; has anyone else found this? I have read some old posts on here detailing a similar problem to mine(2 below the expected amount and nothing left to get) but none have really had a good explanation as to what happened.

Anyone else that can share their experience or knowledge on this?
