Yea I didn't come here to complain about it but I just noticed while playing that sometimes when I was still looking for glimmermoss I would go days without it after finding a lot, same with cave clay there was a period where I just didn't find any for a week. then found a different cave (in a different realm) where I found like 5-10 a day by casually visiting it a few times a day.
also when I look for mussles the first few runs always get me a lot more pearls xd
anyway I just wanted to figure out if it's because of that localized pool or variance.
