I've seen many Mavic, Spark, even Inspires tag a small tree limb or group of leaves and have it go down or spiral off & do down. 
Knowing it doesn't take much resistance to effect Motor or ESC of smaller crafts... bigger platforms too for that matter too.
I recently completed a test Litchi flight, always have it end at 1st way point or hover then manually bring it down. Was in a residential area with a lot of trees and required a little maneuvering to reach drive way. In honesty, I brought it down a bit too quickly while enjoying the tight navigation through the trees.... ya, a bit over zealous confidence was plucked.
Connected with a large maple tree's upper smaller branch at tree top level, so much that it threw leaves and the Mavic went toward the center of tree! With sphincter clamping, I was pushing sticks up & away from center... thinking it was about to stall motor & snag or fall. Could actually "hear" the motors grunt several times as connected with tree leafs, changing pitch like a harmonica; suddenly the little M2P appeared over the top of the tree.
Landing & inspecting the Mavic shown it was well covered with leaf sap on props and fuselage beyond wiping off, required a damp cloth to clean. The props weren't broke but the prop attachment tangs showed large indentations... enough to warrant replacement.
Just passing an observation that the Mavic 2 series appears to be a bit more resilient and able to recover from a small strike.

		 Actually had that off... to drop down throgh trees with OBS on almost isn't possible... keeps stopping and won't maneuver through the trees. It was self-inflicted... if I had been more cautious, wouldn't had occured.
