Usually when we are building in Minecraft we are able to destroy a block and then almost instantly exchange it with another block(doesn't matter which type). In my case I am trying to put cobblestone under a sand block before it slides down. We used to be able to do this, in fact it's how I've been teraforming the entirety of my map area. I had a couple people test on their PS4 consoles and they are affected as well. This is a pretty big hindrance because now instead of putting say, a cobblestone block under 8 sand blocks we now have to break the 8 sand blocks, lay the cobble stone and then replace the 8 sand blocks... times infinity. When doing large scale remodeling of a map this adds copious amounts of time to the build. This seems to have happened right after the latest PS4 update. Anyway, thanks for looking into this. I sure hope this gets resolved or is not the direction you guys decided to go with the future of Minecraft.
