For the record, v0.8.03 should be listed as "recommended". It's the best version of the onsen map. The Open Viva Project version is a buggy mess with a bunch of stuff removed and it seems to be abandoned.
And v0.75.3 is the best version of the ranch map.
Dunno if v0.9.3 is supposed to be a bunch of empty dev sandbox-esque maps but that's all I can seem to access. Fun for just spawning things in and messing around, though.
I was checking in after a couple hectic years and it's sad to see the project discontinued but if you're working on something else, that's great, too. I'll keep an eye on your YouTube channel. 👍
