I encountered a crash that has huge backtrace, it happened like this.
I was manipulating the scene using my mouse, and then i zoom and tilt my scene downward to expose more 3D elevation. Then crash happened. Which has 121, this happened once more and it had 120 backtraces. Don't know why it crashed. Caching is active.
If you guys wan't i cant give the whole backtrace of it.

osgEarth 3.7.0

Thanks. This should never happen :) but since it does, I have pushed an extra null check to keep it from crashing.
