Hey there, had today same Problem, i think. I stuck under the wagon in Fall from Grace, just could take the lure and throw it infront of the guy, he saw me and give allert. Than he shoot me till i was dead. I tried several times, it seems that nothing would help, so i tried to throw the lure at a other moment, when he talks with the other soldier, and try to light his zigarett. Try this, maybe it works, if this is the same Problem you have.
Hey, I found a suggestion on Reddit that fixed the issue for me. Reduce your graphics resolution to low and restart the checkpoint. Your character can throw the lure properly and then you can melee them. Apparently it's a graphics issue. Hope this helps!
