This bug is completely new to me. Each time I try to place consecutive blocks (any kind of material) they are quickly positioned so as to overlap. Make buildings is hindered by this bug, now. The problem is present either with the controller or with the mouse. I had just noticed that the previous bug had been fixed ( https://bugs.mojang.com/browse/MCPE-22362 ) and now... a new problem. This is really depressing.
