Using shears, and even without tools, I was unable to collect the wood from the oak blocks I destroyed. Unable to try using an axe or pickaxe because I had none without any wood. I then downloaded the latest update on September 11th, and crafted a flint and steel (from the inventory craft button), and it just appeared floating in front of me, unable to be collected. My inventory does have room for these. This issue does not seem to occur in previous or new worlds, only in the one I was playing.
