Saves from 1.55 (which I backed up as I always do) doesn't work properly if been copied in 1.65. For example, my last save in 1.55 end with the meeting near Rachel's house with Connie. 1.65 opens the following situation with the scene of this three together and then after it ends, I get announcement that this is all of the available content in this version (end credits, roxy's photo...).
So, I decided to use the save that was in the game folder already. It works. But it is broken in a way too: all the quests seems to work fine, but if you choose to randomly approach every girl (I mean, do the quest continuation of every storyline), you can end up in the situation, where when it's time to visit Kate, the game somehow jumps to the point, where Ray talks with Kate and skips the moments, when you visit Kate twice, got some dialogue with her each time, then you have to watch 2 scenes of what happened while you've been absent (in the memory room). It is a minor thing, but still I would like to have read all the dialogue elements of each story line well sorted in chronological order. I guess, this happens because all events are settled in the same playing day. Not to mention that I have to replay manually some points which I already did in the 1.55 (because of the same play day), which confuse just a little...
Anyway, still enjoy the way the things are going. I mean, the storyline of the game itself. But I have the feeling like it is going to be a loooong time until this game will be finished and that each new version will contain less content compared to the times, when 0.xx - 1.25 was in development.
Don't get me wrong, I understand that it is hard to pursue the development of AVN all by yourself (to be precise, being the two-man team, half of which is represented by a programming chief, according to your patreon info), in the state of current events (heh, GUESS WHERE I AM FROM :D), but it will be better to end each version at the end of a playing day to avoid such inconveniences.
I've written about is many times on our patreon page. One play day usually takes two versions. Saves at the end of the first half of the play day (the previous version) do not work in the second half (the next version). For this purpose, we make saves. And your saves work only from the end of the previous play day.
