Responding to absolute smoothbrain retard because I don't know how to recognize bait.
Frost only collects on the outside where cryogens are touching the walls, and since Starship is only tanked like a tenth of the way for 10 km hops the only places that it actually does so is at the bottom of the main tanks. The "seam" you are describing. Who would have guessed it's humid in South Texas and that superchilled LOX/Methane can be cold through 4 mm of steel???
>smoke out the back
Whenever Starship is about to fire its engines it has to run the fuel through its engines to cool them and prevent flash-boiling during startup (which explodes the engines.) Literally every time there's huge vapor clouds pouring off the rocket it's valves venting to accomplish some purpose or another. I honestly can't imagine having such a childlike view of the world to think otherwise
