Unless the crops are very dry or have been harvested and the 'left behinds' are dying, this would not be so unexpected. After all, the bending of grass blades is how all those designs get made in lawns and so forth. We see it all the time.
You're telling me that mowing the lawn doesn't break or cut grass?
Sorry, but in all of the man-made creations the crops are broken. In the authentic ones, none are broken or damaged..
