[V8.5 Air Combat) Problems with Fighters

Shooting down ufo fighters no longer creates crash sites but after shooting down two or three I now seem to have a >50% chance of the application crashing every time I shoot another fighter down.

Only happens with fighters, not scouts or corvettes, and if I avoid engaging with them it doesn't happen either.

Strange. Single fighters, double fighters? Escorting larger craft or by themselves? There's some odd stuff relating to the air superiority missions that was causing crashes with the saves, so I wonder if it's anything to do with that?

Thanks Chris - to clarify now I've played with it a bit more: all single fighters by themselves and it only seems to be for certain waves of three/four fighters, as if I can get through these by ignoring them then the problem seems to go away and not recur for quite a while.

I've got a save when it happens consistently if I can work out how to upload it...

Right, got it. Crash happens most of the time when shooting down the fighter already on screen in this save:
