Once every week or so, I'll go to chop down some oak, pine, and maple trees and seeds won't drop. This only happens every so often. On other days I'll get anywhere from 0 to 2 seeds per tree, and on these rare days I won't get a single seed. I'm not sure if there's something like luck, foraging skill or weather that influences seed drops, but what I'm talking about is way outside of chance. I'll cut down 10+ trees and get 0 seeds, where any other day I would get 10-20 seeds. Anyone else having this issue?
