Does the campaign system have memory

[IckyATLAS]

When you are in the campaign system where you can go to the next mission if you have succeeded the present one.

Now let's suppose you do not switch to the next one and replay the same one and fail. Will you still be able to retain your first success and still move to the next one or is your initial success overridden.

Once the mission success condition is met - that’s it. The following mission is permanently unlocked.
