My flight was three weeks after the incident at HAM - and quite incomfortable (the bottles at the bar in front of 4E remained at their place, though). I think it was "light to moderate turbulence".

Was your flight a day- or a nightflight, and what about the daylight outside?

There is for sure no rule to close the sunshades just because the flight is a bit bumpy. Such a rule doesn't just make sense.
