If you are a newer player read the update releases before starting temporary quest lines. This game guide is usually updated within 24 hours of a release and also provides helpful information such as a list of quests. You can determine if a release is beyond your capability, harder than you want to try, or something you just don't want to do. A lot of frustration can be avoided if you do this.
Releases that have regenerating items and floating balloons to click often use all three lands: Home, Emptyland, and Dwarfville. If you only have Home available, these quest lines may not be possible to complete. If you do not clear the items, new ones will not appear. When the event is over you may be able to sell them so you will at least get coins. If there is a structure involved DO NOT put it on your estate until you know whether you can complete it.
