We've been complaining about this for a long time already!
We're okay with not every episode having a new map, like you told us, we understand and that's okay, but what's not okay is that each new story episode can be played in less than an hour. it's way too short. each new episode should take at least 2-3 hours by doing story only! and then much longer when doing random map events and achievements (that is well done for now)
there's barely anything happening at any episode at all, many of us like to play a storyline, and this has been asked countless times, so please in the future start making each story episode way longer!
