Star Wars Rebels S2E19 The Forgotten Droid

Did Disney XD forget to air this episode? The Forgotten Droid was a fun lighthearted episode that felt very out of place after the amazing Shroud of Darkness episode!
The mis-adventures of Chopper and AP-5 was entertaining and I enjoyed the parallels to R2 and 3PO's relationship.
Unfortunately this episode did  nothing to move the story along and felt very out of place. In my opinion this episode should've happened early in Season 1.
Lets go to Malachor already!
