It's not mentioned explicitly in the changelog so I thought I'd point that out - at v0.08(I think) teary switched to some form of external event loading plugin system which was not present in the initial versions. Lack of such a system is what makes developing in rpgm really shitty, and to my eye as a programmer it is the biggest red flag present in all similar projects, so I was glad to see teary addressing that. To keep it simple, it allows the dev to avoid copypasting lots of dialogue data across all the relevant maps and reduces amount of dumb busywork and potential errors that come from that.
That said, from missing Beverley events and other bugs I could surmise that teary is not yet used to using that system. Furthermore, it is unfortunate that required bugfixes were not released timely, conveniently or at all. I am hoping teary will take time to figure out how to make small patches efficiently without reuploading the entire 1.5gigs of animated succubus ass and shitload of WIP content contained in the project (I assume that's what kept him from doing bugfixes). To my knowledge, rpgmaker doesn't offer any convenient tools for version numbering or keeping track of what goes in builds and what doesn't, so it's a bit of a bitch and has to be learned separately and done manually.
Regarding v0.09, I am sure everyone could see a number of UI reworks and other engine changes, it was more obvious than the v0.08 thing. Unfortunately, it isn't realistic to expect stable builds from teary at this stage of development, especially from updates that still change the under-the-hood systems. I find it quite unfortunate myself, that I still can't recommend this game in good conscience because of all the bugs.
However, I believe it is not accurate to say that teary is not improving or not trying to address the development issues. It is currently a rough, unpolished mess with trivial mistakes like leaving the noclip flag enabled, but in my eye teary is trying to take the intelligent approach to development and it will pay off in the long run.
