This small piece broke, important?

[Tricky]

P3P, all stock. 65 flights in. Came home tonight after over water flying. Did visual inspection...as soon as I flipped bird over, I heard a rattle inside. Uh oh I thought. I figured at first it might be a pebble that got kicked up and inside during takeoff from dirt/grassy area. I took battery out, rotated bird a few times, and out popped the below. After a few minutes looking very hard, found where it broke off from, it's got a matching partner on other side of battery mount.

The pics suck, I'm just throwing this out there for tips and thoughts and opinions, this is where I learn, from all you good people.
Thanks in advance.

Strange part to break, but should be fine. Its just an alignment pin

Sorry you got an extra piece there. Doesn't look like it will affect use, but be sure to not come in at an angle when switching batteries.
The plastic on these things is rather B.R.I.T.T.L.E
Hoping DJI can get a bit more D.U.R.A.B.L.E with future shells or as production moves forward.
