I've had that happen when i had to place them outside becuase of people looking at the house(for sale) one or two of the fan leaves did turn sideways but when i placed em back into the grow room and flicked the lights on the came bck up the correct way within an hour or two...im not sure as to what the exact cause of this is...maybe somebody else on the forum may clue you in a bit more!
