All planets become Level 12 should be a mega-event

I got this event with mega-events off and I have to say it disupted the game enough to qualify as a mega event. It can seriously mess up the balance of power, especially if the A.I does not take advantage of it right away, which only some of them seem to do. I had to restart the game because the idea of suddleny having 30 planets to colonize and build seemed really tedious.
