Intermittent radar failure after multiple respawns

[prof_laser]

This is OpenBeta 2.5.4.29585.

 

This requires a bit of pretext, since this bug occurs sporadically. I can't reproduce it at will. But I noticed it the first time about two months back.

 

I have set up a mission for my buddy and me to do dogfighting training in the F-18. We start heads on, same speed, same altitude, 9 nm apart. Mission is attached. In the track files we picked the slots at 38 T LN 49 61 (Groups are "Mountains Sidewinder Blue" or respectively "Red"). We go and kill each other, then I pause the server, we go to spectate, select the same slots again, and I unpause the server.

 

In the dogfight we typically start by picking each other up in the radar using ACM and HACQ before merging. But sometimes after respawning, we cant get a radar lock on each other. Sometimes only one player is affected, sometimes it's both. According to the HUD, the radar is directly on the other player, but it doesn't lock.

 

Not only that the bug occurs sporadically, it also doesn't show up in the track files. In the attached file, the bug occured close to the end. When we notice this bug happens, I restart the server by selecting the same map again in spectator mode. Then the bug is gone. After about 10 minutes, it happens again....

 

Since it's hard to reproduce, I will upload a video of the issue.

 

EDIT: Video is uploading. Should be available in high quality in the ZULU morning hours. It shows a total of 5 times this bug occurs.

Changed the title to make it clear that this is a bug.

I have experienced this several times.

That's good and simultaneously not good to hear.

 

Since this bug can't be triggered at will, I think it might be good if we can test this on many different machines. If you read this, please download the mission, grab a friend and play it with him for 30 to 60 minutes. In our experience, the bug should have occured after this much time. Then please confirm or deny that it happened for you.

Confirmed, and previously reported some time ago.

 

The work around is to switch to guns, then back to Aim-9 or whatever other mode you are using.

 

You can tell when it's not working because the PRF selection disappears from the left side of the radar DDI (when it works, you get the HI/MED/INTL option, but this option is missing when the bug is present)
