App Crash when restart navigation

[juanmanuelco]

I have implemented navigation in Mapbox. The first time it works perfect. The second time the application stays on a black screen and in the console it says "Lost connection to device"

I'm having the same problem only on Android... it seems a simple NullPointerException here my logcat:

I think I've found the cause (at least in my case), it has something to do with simulateRoute: true, because I set it to false and now app doesn't crash.

This issue needs attention. Sure simualteRoute: false fixes it, but that's not a solution.
