Mission "Test LV-T45 'Swivel' Liquid Fuel Engine splashed down at Kerbin" Broken
I've completed all mission objectives twice now and while in flight, the game will place a green check mark indicating both objectives are complete, yet the mission won't spawn the completion message, and all objectives keep showing as "incomplete" in the mission control area for this contract.
I'm using the Steam version so it should be automatically using the latest release version.
Take a look at your splashdown photo. Do you see the engine in the staging on the left? No, you don't. This means the engine is not attached to the ship. To complete this mission, you must not lose the engine when you hit the water. Try more parachutes. Lastly, you must stage the engine to test it. You cannot stage the engine before the splash down.
