Snow ball breaks different blocks when thrown.

Please add much more detail to your future bug reports explaining what you did, what actually happened and what you expected to happen.

I cannot destroy blocks by hitting them with snowballs in either game mode.

However, in both game modes, when holding a snowball, if you press and hold on a block within the player's interaction range, the player will throw one snowball and start interacting with that block at the same time. The player will continue interacting with that block until the user releases the press. Since, in creative, destroying a block takes very little time, it can appear like the snowball being thrown is destroying the block, but it is not.

I have resolved this bug as works as intended. If there is something I have missed, please feel free to comment further.
