1.2 Stinger no lock-on sound and dmg

[gdpr_user1]

When using the stinger, looking down the sight to lock on to an enm helicopter you won't hear the lock-on sound indicating locking progress and successful lock.

I don't think it's about the distance to the target that could have been too far for a lock on since one of the helis I tried to lock was not more than 100m away from me.
When I first experienced this I was trying to lock on to a Havoc, no sound was heard but he still flared and flew away as if he got locked.
I let my friend have a go as well and he couldn't hear any lock-on sound/tone either, that chopper also flared and waved off.

To reproduce: pickup Stinger AA kit, aim at enemy helicopter within range.
Tested on Sareemaa AAS, the layout with Cobra, Havoc, Hind and Cashuey.
I can provide settings if requested, on my phone atm.

Another thing I want to point out about the Stinger in 1.2 that I experienced during the same round is the damage it deals to Cow Rus airtrans helis. I "hipfired" the stinger (giving it a straight flight path) at cows on two occasions, hitting them centre mass as the missile exploded.
None of them were even smoking after the hits...
Neither of the cows dropped any flares that might have "absorbed" the damage.
Curious to know if this could simply be netcode/lagg issues or if you have in some way reduced the damage in 1.2.

Thanks for the report.
The missing lock sound is my fault, sorry Fixed it right away.
That it didnt deal damage is most likely netcode related as you said, in the code nothing changed.

Killed BTR-60 with 2 stingers yesterday so damage should be fine.
