I want to report that this still is an ongoing issue, though, apparentely less frequent.
And I'm reporting a new sound bug.
In Beirut, every now and then I randomly hear a TAR-21 auto burst close by. It's like a far away sound playing in the wrong place, way louder than it should had. I was doing some spotting in the western apartments, the ones that are closer to the tunnels and the big shipyard on the west island, there it's very frequent. It drove me crazy, since I heard gunfire close by and by no means could I find the enemy, because there was no enemy. This only happens with the TAR-21 in Beirut as far as I can tell.
I couldn't find a way to post the stats below as a spoiler, to save screen space. Can someone make the text below into a spoiler?
