Im lost.. so where do I go to replay missions?

If you go into your Ready Room on your Bridge you will see a computer on your desk that will let you gain access to the feature. Then you fly to the sectors and do them.

Edited for snarkiness.

Nm I see it in the release notes.. I must of completely missed it.

Will there be a later update allowing us to replay patrol missions (Fed) or empire defense (KDF)? The former cannot even be shared by other players.

I wouldn't mind replaying patrol missions. I have enjoyed Episode Replay since it's given my VA's something else to do

So... several months back they said they held off on releasing episode replay because of problems with sidekicking and level scaling... and the replay episodes still don't scale at all. Yay. That helped so much.
