I posted a NT 8 exception a couple of weeks ago.
I can't find the post here's another:

2018-03-12 08:58:38:689 Shutting down NinjaTrader
There is nothing else in my Trace/Log files.
This exception is at the core of your low-level libraries. They need to be re-written.
I shouldn't get exceptions when shutting down. I don't think this is ready for General Release. I am planning on moving back to NT 7.0.
