Air to ground weapons (GBU-8)

Weapons lock is complete failure. You go to targeting view, find target, lock it and then for some reason it lock to random ground dirt patch. Any ideas?
PS. Devs should add complete guide how to use such systems

There is a system to test weapons with information on how to.

Go into modification of your aircraft, clic on test bar under the weapon you wanna test/tutorial about.

GBU-8 is a TV seeker System → it needs a really good visual over the targeted vehicule

And if it losses track, it will end-up as a dummy bomb.
