every route tells me I have to visit the hub since r30.. wtf is this? its now r32 and the game is unplayable still
The game tells you can save when you reach the hub, not that you need to visit it.
It's a message displayed when you reach the end of a build, some are leftovers of previous builds that I need to clean up, clicking on Bell to display the current objective is the most reliable way to know if you've reached the end of a build.
As I've said in the previous message, each build after R25 has been focusing on finishing each heroine's route.
This means if you are in Hestia's route which has been finished on R27, if you will try to load that save and play on R32, you will still have no new content to play because at that point only the game's ending is missing, which will be added on the final release so you can import the save into the sequel.
When it comes to R31 and R32, I've actually made a devlog on itch.io detailing the changes:
You must be registered to see the links
So if you were on Eina's route, you'd have new content to play.
If you were on Haruhime's route, you'd find two new scenes in the Dungeon.
And finally if you were on Harem's route, you'd also have new content to play.
If you are in none of those routes, then obviously there'll be no new content.
To save you up some time, R33 completes Airmid's route and adds a new Cassandra scene, whereas R34 adds the first hentai scene with Artemis and completes Cassandra's route. R35 released on January will complete Artemis' route, which is the last one left.
If you are in none of those routes, simply wait for R36 to release which will be the last build containing the ending.
