1968 Farm Heroes is not possibe to get. Please simplify

Agreed. Seems the 1900 series of levels has one impossible level after another. Why?

The game is starting to waste time. It seems that only a few people are the leaders who have reached these levels and every 2 to 3 levels we hit the wall! Crawling to pass it and waste our time or complaining for it to be fixed after two days. I suggest your team to start revising the available ( not correctly calculated ) levels, instead of releasing new ones every two week. 

I am presently on 1971 and levels from 1968 onwards are ridiculous. What is the point of levels which are impossible? 1968 and 1969 have been revised but now I am stuck on 1971. It's just so off-putting and I am waiting for 1971 to be changed. There's no way that I can pass it in its current form.
