Default [CHECKING] AIM-9M Lock-on Issues

I have been having issues getting the AIM-9M (and have seen this with the X but not thoroughly tested yet) to lock onto aircraft even in favorable conditions.

I had tried this both with the un-assisted boresight mode, uncaged the seeker and it will start to growl but not lock on most aircraft. Similar results occur when using the radar-assisted mode.

Conditions testing have included from 10nm initial down to 1nm in both head-on and tail-on aspects.

Aircraft I have had an issue with:
-SU27
-MIG29
-L39
-F/A-18C (following a friend online)

In some cases it still does work, for example swooping in on some friendly AH-1s I had no problem getting a lock.

I will try to make a shorter track if possible, currently my MP tracks are over an hour so unsuitable for bug testing.

Sorry, but I cannot reproduce this here. Kindly provide a track.

Some targets, like a helicopter with heat dispersion, will naturally be more difficult for an IR seeker to track.

Thanks

Wags,

Thank you for looking into this. This morning I have spent some time trying to narrow it down.
So far these are the conditions:

-Multiplayer Only
-Must perform and A/G release first, I used MK-82's in CCIP.
-Subsequently AIM-9 seeker will begin to track, but not lock a target.

Since I had to be in MP, the track file is about 14MB, too large to upload.
Please see a copy of it here from my OneDrive:
https://1drv.ms/u/s!Au6nuN4_FUp2gqIg...-aKDg?e=ukW6sr

In the track I attempt to lock both from a head-on and tail-on aspect, caging and uncaging the seeker a few time to make sure it's trying.

I was able to watch the problem in the track file myself, locally.
Excuse my takeoff, I had de-selected the DCS window by accident!

In a previous flight / track file (not uploaded) in the same mission, flying head on with an L-39 in the same fashion without first having done a CCIP weapon release did not recreate this issue, and a valid lock was acquired. And of course, a tail-on aspect was also no issue.

Using the same pattern in SP (although with an air start) did not reproduce the issue.

Nineline,

Tried again with the new hotfix.

Not only does CCIP release of the Mk82's seems to work properly again so far, the sidewinder seems to be back to normal too.

I'll add to this again if I see this return.
