Anybody can now use tnt and such and it has no effect on many crafted blocks. But I tried to use tnt recently and noticed that I can only blow one up at a time. This makes sense in order to reduce griefing, but if I need to blow up a lot of things (let's say hollowing out a mountain hypothetically) then is there a way to make it so I don't have to flint and steel each piece of tnt? Do I have to get supporter, or change difficulty, or is it just not plain possible? If anybody could help me with this, then thanks
