The ability to extract from Wave-based Challenge missions#596

Currently, the only way to redeem your rewards is for the gauge/Wall health to drop to 0. If you die, you may either use a continue, or exit with no rewards. You’re more likely to get killed than have the Wall break first/Gauge drop to 0.

My proposal: Only for wave-based challenges, allow us to extract when we die and keep all the rewards we’ve earned.
