Comment #1 on issue 424 by bre...@gm...: AI objects in scenarios  
re-loading far too often without unloading, cmdarg().getPath() becoming  
corrupted.

Also, models loaded via AI scenarios keep appearing and disappearing more  
or less randomly, even when very close to the main aircraft--like just a  
few hundred yards off.

They seem to unload almost as soon as they are out of view and then when  
they come back into view (either because the main aircraft turned or you  
are just looking around in different directions) there is a pause  
of "invisible aircraft" before they suddenly pop into view.

At the same time, there is a definitely pause/halt/jerk in the graphics and  
framerate.

I think this is related to the problem I described above because the models  
often seem to try to re-load at (or about) the same time they re-appear  
visually.

To see this problem, load about any scenario in the bombable package (as  
described above) and fly around as though engaging in a dogfight with the  
other aircraft.  You'll see the other aircraft 'invisible' and then popping  
back into view numerous times.
