Hello! Yes, they are missable. In 0.2.4 there are more than 10 sex scenes in total, so you definitely missed out on a lot
Yes on 0.2.6 you will return to the town. It will also have the first pregnancy scene.
Yes it has been reported. I have no idea why it's happening. I will need to recheck the UI. I tried finding the root cause but I'm still not able to understand why it's acting like that.
I haven't, I'll check sorry, I've been really busy this past weeks.
It will be on the week of the 19-21, same date 0.2.6 will be released. So not the upcoming weekend, in the other weekend
