I am playing on an 1.8 multiplayer server and have the same issue. It is only happening in one specific chunk. In that particular chunk, when I try to destroy a block, it reappears as if it was never destroyed. If I place a block in that chunk, it just disappears as if it was never placed.
However, another player was able to do changes (plant trees, destroy/place blocks etc.) in the same chunk. I am also unable to open doors, chests and use a crafting table. But anywhere else outside that chunk, everything is fine. So what is causing this particular issue to make me experience such things? Is the world corrupt? Is it caused by lag? Or is it an in-game bug?
