BIG bug(s)? in ME and offline - tried to run modified mission (it used to work)

-90 degrees angle of attack, mad dives/superzoom climbs, standing on each others' tails... 

Here's the link to the mission file:

The only things I'd changed from the previous version (which worked) were that I'd shifted some waypoints to try and ensure that all the planes engaged in the furball (but the problems occurred long before the problematic set of planes reached these waypoints), and I'd added some C-47s (for fun) and P-40Es.

I just tested this in offline mode, it worked ok until the game crashed.

I got these screenshots:
This was from a few seconds before it crashed.  Please see the film for further details.

This was from a bit before it crashed, before I took off-not sure how relevant it is

And this film:

I'm fixing to do a write up this weekend on many bugs/issues I have found.  Being so new, there will be bugs, but I think there may be issues Sudz isn't aware of, or may be able to explain.
