I had just finished clearing out an American task force in KB58 near Christmas Island when I got a navigation map update indicating a nearby survivor. I was a short distance away, so proceeded on the surface to the survivor's position.
Though it only took about two minutes realtime to get to the indicated position, I was unable to locate the survivor. I started following the slow drift course North and found two empty life rafts, but no other signs.
I eventually gave up visually searching and requested a scout plane from Surabaya and surprisingly, the scout plane accurately reported the survivor location once they were in the area.
When I reached the survivor, they were bobbing in the water without a raft, and without smoke.
In Version 1.3 we had difficulty locating drifting survivors, but we were able to submerge and detect via SONAR.
In Version 1.4 we lost the ability to detect via SONAR but we were given red smoke to help visually locate survivors.
In Version 1.5 it appears we've lost both the SONAR and the red smoke.
Other than calling for scout planes, has anyone found another means of locating drifting survivors?
