I've noticed that a quite a few of your extra challenges crash on iPad.

Currently the Windmill challenge crashes EVERY time I play that level.  Not only wasting "energy" but making it so that I don't even want to play.  I know this has been an ongoing issue, as I have read complaints about it in Facebook months ago.  Extremely frustrating that you've done nothing to correct the issue.  I really wish you would.

Same here.  Trying to play segment "ignite the light" and it crashes every time, losing lives.  Have not been able to play any of these extra segments for a long  time now.  I used to recommend Farm Heroes to friends, but will no longer unless this gets fixed.    Frustrating.!
