Ok so my buddy and I were trying to find a few raiders and we couldn't find them so we wint really far down and I xrayed (not saying that you should do that but they were getting too hard to find) and since I xrayed I have been able to walk through upper blocks with ease. It may be nice for some things but in all it is very quite annoying so please fix this. EDIT:I have reloaded my world, restarted minecraft, and my playstation. It still happens
