It does seem to be fixed, indeed. Now idiots like me can get stuck without a get out of jail free card. Just a joke, but I would recommend maybe adding some way to automatically process dirt that you chunk out (but still make it so you have to mine ores and all that). It is possible to destroy a save by getting stuck in a hole with a giant block and nowhere to set it down. Example, here - I am not capable of placing down the block where I was, Jumping up and placing it above the world, and it's too big to fit into my backpack. As far as I'm aware, I've softlocked myself. Now, I'm not saying you have to fix it, but it is a possible problem you may not be aware of. Anyways, keep up the good work with the game.
