Hmm, I'm not sure I'm understanding some of the issues you've reported here.
1. In regards to durability, Mend is MEANT to be an alternative to spending gold. Of course you appear to have an issue with that skill but I'll get back to that. Sewing items and gold can both be found in chests and crates. And of course gold can be made via side quests, lewd events and even selling items. There should be plenty of gold to go around to buy various things as you need them.
2. I see the issue here. The Goddess Statue in the lower levels of the mines is what is broken. Interacting with that will give you an incorrect respawn point. I swore I fixed this previously but I'll make sure this fix is reflected in the update this weekend.
3. Now I tried with multiple save files, and different goddess statues, but no matter what I did, Mend always displayed and functioned properly. So I unfortunately have no idea what's going on with this one. At least, it wasn't something that I was able to reproduce. So if you have any more details you'd think would help here maybe I can figure out what happened.
4. As for the magic items I'm not entirely sure I follow what you mean here either. I thought magic items might have meant the throwing dagger or dragons breath but both showed their animations for me. I then tried MP restoring items which also worked fine. So what exactly did you mean with this last point?
