So, I has playing the MiG-21bis “Lazur M” today and I was experiencing a strange bug where the R-3R radar missiles here behaving like IR missiles. What I mean by that, they only give a positive feedback (the red circles arround the target) when you drop below 3km in rear-aspect, all the while making the SFX of IR missiles.
I’m posting this here so you guys can also test it, but I already made a bug report available here
