SP and MP Server Crash with AT-11 (T-90etc)

[MartinCo]

Hi ED,

Since DCS 2.9.8.1214 (It's hard to say if this was also in the main release, but for us it only started experiencing after the hotfix)

We have had 4 dedicated server crashes all with the same stack trace below causing significant disruption on our multiplayer servert90-crash.miz

We have managed to reproduce in single player too (Miz file attached) which has just 2 x T90s engaging 1xAbrams with AT-11 whilst you fly in the vicinity and the crash will occur - sometimes it's fast, sometimes slow - could be related to AT-11 missiles vanishing after hitting the buildings.

This has occurred whilst flying both the CH47 and AH64 (I didn't try any more modules after confirming two) 

First track whilst flying CH47, and second track (even faster crash 1545) with the AH64

In the meantime, we have disabled T80/90/ZTZ s etc. just to limit the risk of recurrence.

Thank you, reported for internal analysis.

Had the same Crash after killing a Tunguska with a Vkihr missile. 
The mission was run on a dedicated server.
