Try this thread https://forums.teamlava.com/showthrea...l=1#post201761 This gives some of the ending goals so you can place items early. Once I got the lip couch most of the goals went fast but I think there is one long time items you need to put down.
Let me go see if I can find a thread with pictures. My understanding from the posts I have read,is even though you miss a timed goal, you should be able to continue on to the next goal, you will just not receive the lip couch. Now that you missed the time goal, what are your next goals?
