Yep, yep. Some of the biggest updates in the industry. One of the largest 2D novels in terms of content, characters, kinks, and so on. Tons of work, and they've reworked old content more than once.
But yeah, inconsistency. Oh, the inconsistency! Iron-clad, damn-near unbreakable inconsistency.
Let me ask a rhetorical question. You do realize that for such a massive world (in terms of the novel), smaller (and thus more frequent) updates would feel like scraps in an empty world, right? I mean, you'd get 1-2 relevant events a day, then go to sleep- and just rinse and repeat.
They've boxed themselves in, making it so updates have to be huge (yeah, I know a lot of people wanted even more, but what can you do?).
