TechRacer: Fix gears not spawning on turn start when player pressed control right at start The activationStage was horribly programmed and heavily relied on timer. There was a sweet spot at turn start that if you managed to push a key right at the start of turn, you skip the Ready phase and the activationStage would advance, causing the gear spawning code to be skipped. This fix greatly simplies the spawning phase.
