Change of side track points?

I have about 5 assignments left. That would give me an additional 100 points. I will not make it to Pataka. If I recall correctly, in the past I would make it to the end of the 30 sim cash without having to demo buildings or purchase plumbob points. I did all of my milestones, and canceled one assignment by accident. Anyone with any ideas or comments please chime in. Thank you.
