Re: Quests, tasks and timing.
too late for the one you missed but it will return
In the future
read a head, so you know what is coming, how many sims needed and what the days look like
If it is a re-run, google the quest name along with the words sims freeplay and look for the girl who games
For the upcoming seasonal quest, look here
The days are long, the tasks are plentyful
but with a bit of planning, it should be doable
Rush when you need to save time, plan which tasks to rush, the multi-sims ones are very expensive but rushing shorter 1 sim tasks are cheaper (if the task is 2hrs 20min, wait until the timer is down to 1.59 to rush it for 1 LP)
Use timers
Look one day a head and plan your day, what to rush and so on
Good luck
