F1BE Multiplayer crash.

[Tengah]

This is an initial reach out to the community regarding the Mirage F1BE crashing when crewed by a student and an instructor in multiplayer. 

Flying the Caucasus map.  All other multicrew aircraft are performing flawlessly: F-4, F-14, C-101. 

The Mirage F1BE is causing a solid DCS freeze for both parties flying the aircraft. Has anyone else experienced this? 

The freeze seems to occur at altitudes above 8000ft barometric. 

At the moment, I am trying to figure out if it is a local issue (I do use a minimum of mods - CH -  in the mission) or if there is a recognized problem with the BE being multicrewed in MP.

Note:  Both parties flying the aircraft are new on type; the pilot is using autostart, then the instructor jumps in when autostart is completed.

Any responses would be gratefully received.

I know there's an active issue with CTD if flying above 20K feet in the F1 that has been acknowledged and will be resolved on the next patch. I wonder if your issue has the same cause (and hopefully the same fix).
