Because I swear I had two very clear instances of it this morning. Took a few hits from a direction. Turned and panned around; nothing there. Took a few more hits and died. Killcam showed the guy RIGHT where I was looking at. There was no cover in this area for him to hide and peek. Other time I checked a corner in the library part of the church on devastation. No one there. Crouched down near the corner to reload and got knifed from behind. This isn't the first play session I've had where I've felt that soldiers didn't show up until after I had died. Am I just having serious visibility issues or is this actually happening sometimes? This seems to happen at all ranges every once in awhile.
