TNT Cannons no longer work.

I went on a world today and decided to make a TNT player cannon. However, when I activated it, it didn't work. I made a standard TNT cannon as well but that didn't work either. The 'propellant' TNT exploded but then the 'bullet' TNT entity moved nowhere. As TNT and players are both classed as entities I'm assuming that this is something to do with entity physics.
