Also getting this bug. This mission I'm on is cursed, game decided suddenly that the probe was out of comm-net range despite me being just outside Kerbin's SOI, and sending this exact probe model to Gilly without ever losing control. A quicksave and quickload fixed the first issue, but then started getting the bug as per the thread. Made it all the way to Ike but the game won't let up on stopping me transmitting the data . Retracting/extending the antenna does nothing. Save File

Was able to load a previous save from before the bug occurred which let me save and launch craft again. However, after 30-60 minutes of playing I was once again unable to save or launch new craft. Very frustrating

Didn't work for me unfortunately (no NaN's in any of my saves). I did seem to start getting this issue after the already well documented undocking bug, but loading a save from before the undocking attempt doesn't fix it. Does the game just not want you having multiple active missions ?
