Just played a wildcard flush house but didn't get the Flushed achievement on steam. Guessing this is an issue for all wildcard only hands that aren't a flush.
#Wildcard Flush House doesn't count for the Flushed achievement

Yes, it needs to be exactly and only a flush, not a flush house, straight flush, or flush five

Lucky I managed to get the achievement on the next round but really feels like any 5 wildcard hand should trigger the achievement.
