Anyone know the answer to these questions?

1. If you join a roulette right before a reset and finish it after the reset, do you use the previous day's roulette or the new day's roulette?

2. If you join a roulette as an adventurer in need and the needed role changes while you're inside, do you still get the AIN bonus? (Go in as tank, and the AIN changes to healer while inside, do you still get the AIN bonus as tank?)
