DCS.exe Crash trying to kill Flak 30 and 38? (2.2, Charnwood, P51, VERY low Alt pass)

Four times now I've had DCS crash almost exactly as I've passed very low over a FLAK 30 or 38. By very low I mean under the tree line just about the time I cross over them or just after. There's a small chance I may actually be hitting them... but it crashes a little after I get over them. Either way... It seems reproducible so far although I have not tried to just place one in the ME and do some testing.

I've killed quite a number of them with rockets, bombs or guns... but always from a bit more distance. Each time (4 so far) I've gotten REALLY close to the ground as I pull out just after the AAA it has crashed DCS.

[Minor SPOILER]

Two times with the FLAK 30 just ESE of the objective in Mission 1 <-- Screw that guy BTW...

Two times with the 18XFLAK 38 group ~1K SSW of the objective in Mission 4

I'm wondering if I'm breaking a tracking equation in the AI or something? Maybe moving through an engagement arc in a way it doesn't like?

I'm not sure but...

Anyone else have any issues?

After looking at the log file I see this near the end of the .txt file...

Maybe I'm onto something with the firing arc and/or equation issue? IDK.

The rest of the crash dump is attached. I removed the TRK file... I think it was too big. If that's needed I can upload somewhere.

I have the same crash, but I tested against the flak 36 and 37.

it seems to happen when the player is in range of the AA weapon and their line of sight becomes obstructed by trees. I plan to do more testing with other AAA systems outside of the WW2 units.

So far my crash has happened when within LOS of the FLAK unit and the pass is so close I'm not sure I could fit a tree between us anyways :).

But a tree can be in the background...

I'm not sure I understand what you mean Solty...

There are trees all over the place when it crashes. Foreground, background, sideground :)... I'm just saying that for the crash I've found there are definitely not trees between me and the AAA when the game crashes.

I've done more tests using Flak 18,36 and 37 against several types of ground targets and air targets. The results have been inconsistent except for the fact that the Flak munitions are impacting near the ground. Sometimes Several impacts happen before the crash, sometime its after the first shot.

I too have been experiencing crashes related to ground attacks against targets defended by 30 mm flak lately. More than 3 occasions in the last week.

Is there any way to get this moved into the bug section? It seems reproducible and is still happening.
