... So I take that to mean you haven't done it...

A touch of sarcasm maybe? :wink:
A bit deserved I guess.

So I DID try it and it worked.
You say it didn't for you? What exactly did you do?

I opened a mission containing the objects I wanted in the QMB mission with Notepad and just copied and pasted my [NStationary] and [Buildings] sections from that .mis file into a stock QMB+ "None" mission .mis file for the purposes of this test. (Same map obviously) I also chose a "None" mission as it usually doesn't have any ground eye candy. The objects showed up in the FMB and in game as well. Mind you they were nowhere near the waypoints of the None mission so I had to fly a bit to find them but find them I did.
You should be able to copy/paste "Chiefs" and "Chief Waypoints" as well.

Once done you'll want to go into the FMB before playing and see if any conflicts were created like side affiliations and objects/Chiefs on top of each other.

Really nothing special I found to make this work. You may need to alter waypoints in the merged mission to get your flight(s) and enemy flights near your objects but other than that.....

Perhaps if you can be a bit more specific about what you did I or someone could be of more assistance.
