Bug found!
While in the Advanced flight model, I am unable sling load any object. The rope drops, the sling load cam works, it latches the object. but when I go to life, the object doesn't move and acts like an anchor.
When the object is still attached, when I switch to standard mode, I am able to pick the object up and move it as you'd expect, but when I switch back to advanced it just falls and brings the Helicopter with it.
it happens with all helicopters, mod-ed or not. and no object can be lifted, vehicles, ammo box, ect...
hope to hear solutions or hope this gets fixed soon.
