Rockets never reaching planet

after redirecting rocket back to orbit, it did eventually get there, and was able to land it using rocket pad on surface.

 

seems to be intermittent. as it didnt happen on the return trip

 

I had something similar happen to me. The rocket said it landed but the rocket was not in my home planet. I could not launch the rocket again. My Dup was stuck in limbo, not flying or landed. I rebooted the game and found the rocket on its rocket platform with my dup inside.
