This error prints out over-and-over as soon as the scene starts.
Assertion failed on expression: 'changeMask != 0'
Any hints?

Removing all Agents from the Scene didn’t help and it eventually stops without issues that I can determine.
It looks like an issue with transform hierarchy optimizations in 5.6b - please report a bug + repro. project. If you post the case # below I’ll relay it to the developers in charge
I’ll report the issue; it appears to be unrelated to Navigation (as you suggested).
