I was doing a survival on Minecraft Windows 10 Edition planning to build a tree house from Dark Oakwood Tree when I noticed on some of the wood, you were able to climb it like there were a vine on it. There were no vines whatsoever near the tree. I'm not completely positive if this is intended, but if so, this is rather an annoyance when trying to walk up a spiral stair case made of Dark Oakwood and you can barely walk up it without getting caught on what I like to call, "Invisible vines!"
