Extraction fan not worked for 4 hours

Hello my plants are in week 5 of flower and today from morning i must have touched extraction fan cable which came loose and not worked with closed tent for exactly 4 hours humidity was 93% when i opened tent immediately i opened window and turn fans on humidity dropped under 50 with good airflow.Could these 4 hours with really big humidity and no airflow create bud rot or some other problem ?

I wouldn't worry about 4 hours of high humidity I doubt very much a one off could cause you problems.

If there was no rot before you should be fine
