I'm pretty sure it never went away to be able to be "back". I've had this issue off and on for as long as I can remember, including current DLC, last DLC, DLC before that and so forth. Sometimes the X at the impact point is missing, sometimes the trajectory line itself is missing, sometime both (as you have shown). But as I said, I'm pretty sure that has never been fixed. If it has ever appeared in a patch notes thread, it shouldn't have because it has never been fixed.
