I was playing on a really nice survival world that I made and it has a lot of cool stuff in it. When I got into the world after getting off, I was not able to collect items from any sort of block. When I dug dirt, I didn't get any. I mined some wood with a iron axe and still didn’t get anything. I also couldn’t regenerate my health. Can someone please help me? I really like this world and don't want to have to leave it for sure.
