Update on this issue. I have tested it more. Basically on play back the nose gear stays in whatever state they are in at the start of playback. E.g. If playback started after gear up on takeoff, only the main gear, not the nose gear, render on playback, even at times when gear were down. However, if playback is initiated before gear up, both the main gear and nose gear render correcty on playback. Should be easy to replicate. Just take off, do a replay in external view before gear up (nose gear renders)-->continue flight a bit more in realtime, put gear up and do another replay, rewind-->nose gear does not render.
