Speed Up Tokens

My storage was 230 and I started with with over 100,000 in coins and 1500 in dollars.  I noticed something however, the longer I play in a single session the crazier my task requirements got, but then if I closed the game and reopened it the task requirements were more reasonable.  For example, 10 Ice cream sandwiches for 3 points became 4 Watermelons for 3 points.  Unfortunately I didn't notice this trend until after the first 10 to 11 hours.  

So far with 3 hours left I have 135 of 160 points.  All the tasks that remain require 4 to 6 hours of production time for 1 to 3 points, and I've already spent over 1000 Sim Bucks on buying down production times as the only viable means I could see to completing that task.  I estimated out given the tasks I have what I would need to complete.  To buy enough stuff to complete the 3 point tasks takes about 150 sim bucks.  To buy enough sim bucks will cost quite a bit.  

At this point I've sold all the special items for more coin, depleted my coins AND the bucks.  I sorta feel like the only options in front of me of are pony up $100 or fail and have absolutely nothing to show for it.  I could probably rebuild the coin etc in time, but the knowledge of how many bucks and resources I p***ed away is going to eat at me.

The only advice I have for someone still playing is to avoid long sessions.  Log off and back on again and it seems to make the objectives more within the realm of reason.  Inventory also seem to be affected but I was unable to consistently reproduce it   For example 1 task required 5 ladders and I had 1.  Upon closing and reopening the app I had 6 ladders and the quest was completeable.  Other times things like my shovels would disappear.  I was making sure not to use anything that required them, and I was producing them with a speed up token.  After collecting the 5th one I went to check the count  and it said 1.  I logged off and back on and magically I had 3.  Not as good as 5 but better than 1.  

So far as I can tell the problems only seem to occur when you've been playing for an extended period of time in a session.  What constitutes an "extended period of time" I can't say, but at least once every 30 to 60 minutes I'd recommend at least closing and reopening it.
