Sometimes, the crash report of Minecraft will be created, but not shown in the launcher.

I crashed Minecraft ( by '/summon Fireball ~ ~ ~ {ExplosionPower:1000,direction[0.0,0.0,0.0]}') and, normally, it will show the crash report within the launcher itself (I have my launcher visibility to 'Keep Open', so I don't know if this is also true for other options), but this time, it just closed Minecraft, and so I looked in the Development Console, and it said it created the crash report. Random thought: How would new players know what was going on? They'd be awfully confused. :/
