I've so far hosted two house parties, a dinner party, a baby shower, a slumber party and about six funerals and I can never get any achievements. It always says the party or event was a fail. I don't get any tasks show up in the parties and showers and the funeral tasks show up and I do them all but I still never get the bar to move up. I even cancel any conflicting events that might be happening the same time like The Lottery or Talk Like A Pirate Day.
Edit.
I hosted a funeral and was able to achieve a gold reward this time after editing the tasks from the minimum of three to seven. I also hosted a birthday party but there were no tasks available to complete the event. This time I took a photo and have attached. I also filled out the form but it came up with an error message which I've also attached.
