I wan't to transfer to mediterranean and sail through Gibraltar. If change flotilla in St. Nazaire my sub is hauled by rail

to Salamis. Can't change flotilla except in home port so no point sailing to Salamis and then back to the barn at St. Nazaire.
Then I rememberd that once upon a time in Atlantic it was possibly to teleport back to base by hitting ESC button. So I sail close to Salamis but not too close, teleport to St. Nazaire change flotilla and get rail hauled back to Salamis. Voilą I penetrated Gibraltar.
Now if I hit ESC I only get two options Abandon career

or Continue mission.
How do get instant teleport "on" again?
