Problem fixed in 1.78, laser and guided shells are working correctly, at least in the editor :)

Problem still present in 1.70. Seems like only the new jets are not affected.

Before 1.70 the laser shell was "working": was locking on any vehicle in the splash area, also without laser, as the guided shell was doing.
In 1.70 laser shell and guided shell are acting like normal shells.

Same issue here, also jets suffer from same problem, version 1.54 .

In addition "stereo variation" is delayed sometimes also for some seconds.
E.g. if i turn the head when engine is going off i can hear in the left ear what i should hear with the right one, so you can't understand from where the sound is coming.
