Summary:

Cobble Clicker is rendered unplayable due to a change in how commands parse target selectors. @e[type=Player] will no longer target players due to the capitalization of P in Player.

Impact:

Cobble Clicker is currently live on the marketplace and is our best-selling and most well-received piece of content. 

Repro Steps:

1. Download Cobble Clicker
2. Create a new world
3. Notice how the player is continually killed, because the @[type=!Player] selector is not being obeyed.

Observed Results:

Player is targeted by a kill command when they should not be, making it impossible to play the map

Expected Results:

Target selectors should not be case-sensitive for backwards compatibility.
