The dev route for this game is so strange. The updates have been a little fragmented, so I can't recall perfectly, but as far as I know, this one mainly seems to have integrated the investigation at the baron's castle with the regular missions. I think there are a few scenes added in between old missions, but nothing really vital. Doesn't seem to be any progress on the rest of the missions that were there - the castle murder mystery, Kagera's kidnapping, etc all still end at the same place. No real progress I can see with any of the sidequest ladies either (other than some more conversations with Ilga).
I know they're treating it as an early access game, but while that method could work for more gameplay-driven games, it doesn't make for a good experience for a VN. Really need to have the story outline done beforehand and not have to revisit it and break the flow with every update. Not to mention, it doesn't read the saves from the last update, so had to do the custom start and go through the story again. Then again, considering there's no real story progress, if I'd loaded my previous saves, I'd probably have come straight to the game over screen. Shame, since the characters and scenes are great, but the way the game is being developed isn't ideal for active players, and I'd wager that you'd still have a wait a year or two at least to get a full episode that doesn't need further tinkering.
And whew, the RNG on the game is a bitch even on Easy mode. Had to edit the script to bump up my HP by 10x, and then put the fights on autocombat.
