I’ll keep looking at it, but that’s really strange. The discovery flights are normally locked into the weather/time/plane conditions, so it shouldn’t matter what the time difference is between where you’re at and the time set in the flight. I just did a quick test of that flight, and it’s about 2200 hours local in Italy right now, and I didn’t start in darkness.
I’ll see what else I can find.

Have you opened anything in dev mode??
