Flags are not persistant

[justspace103]

Just did a mun mission and planted a flag, but after recovery there doesn't seem to be a flag in the tracking station.

I can confirm - it was the same for me

Also confirmed - just had this happen.

Yep.  

And just as annoyingly, flags planted sometimes don't respect your choice at the start of the campaign and revert to default KSP flags. Sometimes when you plant the flag it's your custom selection, sometimes it's the KSP flag. Once today, I landed and planted a flag on the Mun, then saved my game and closed out for a while. When I came back and reloaded my save, the flag I had planted was still there but it was the KSP default rather than my specific flag, which HAD appeared correctly before I saved my game.
