Hi, I have met this bug with version 4.2.8 (pro) so I thought I’d post it here (since I didn’t see a bug report specific section in the forum). I’m on Unity 2019.1.5f1.
NullReferenceException: Object reference not set to an instance of an object

I think it might be related to a NavmeshCut component I have on my door. I also noticed it’s marked as NavigationStatic in the inspector (at the top) which is weird since I didn’t do it myself and it’s definitely not supposed to be static.
