I make TNT cannon.

But I found a bug and will report it.

On version 1.14, I dispense tnts by dispenser to block(dispenser) which with air underneath, and the tnts fall into under the block.

Like this. (It's hard to understand, sorry)

It's cross-sectional view of TNT cannon.

Arrow mark is dispensing direction.
