Startflag on a tree

Maybe a minor issue, but its happen in the first minutes of the game. Usually this time has to be a perfect user experience (“Oh, i played for 5min and have already 2 Bugs, awful game (bannensoftware)”).

Other notes. This is also possible with moveing the starting banner or placing/moving the “wooden safety standard”. Happends to me on medium oak trees (not on every, just some, dont get a pattern) and small oak trees.
I was also able to place a Sign on the side of a “medium pine tree” some voxel are possible for placement, some not. see screenshot.
