Thanks Xcom.

I think given the new setup I had missed the "use these settings" but I was always under the impression that was just to apply to the settings on that page. (Always had it turned off though, just in case).

Either way, I currently have scenes set to high, as well as locked on high... and that "use these settings on all missions" disabled.

It's configured that way now.

Also, I noticed somehow a bunch of vehicles in that mission were late activated... and had no trigger to activate them. Not sure what that was about... but anyway- I've brought them back in and also configured to "view all" in the F10 view so people know where they need to go to test / kill things.
