Hey idk if this is a bug or not (I might just be a bit dense) but some signals from the signal downloader wont save for some reason even tho ive been fine downloading signals before this one signal, idk if it helps but I'm on day 5.

I never tested what happens when all sattelites have 0 out of 4 packages (basically not functioning). I guess that when you have all satellites functioning it equals to 100% downloading speed. If you have zero satellites functioning it means 0% download speed. But these are just my speculations, I haven't tested that. But definitely maintaining all satellites is necessary as well as calibrating them with 'sd.calall' command
