They don't even have the full version. It's beta test build, testing for bugs, glitches & such that we need to fix. It will come out for everyone, we still don't do release dates.
It comes out when it comes out, we ask you all to be patient. You all will get your full Night 2 update for free eventually.
Patreon one doesn't even include H-Scene or night call. It is test build.
Edit. Yes, other nights will come out for free too.
