Hey! Thanks for the feedback! I'll check that Buckman thing and see if a fix will make to the next update...
- The mines ghost is not a bug, sometimes it just patrols further down the mines.
- It's the first time I've heard about the item bag problem. There is this mysterious bug where sometimes the menu blocks you from using some items, but it usually goes away once you walk around few rooms or so. Or go to a battle or something like that. I'll still look into what could be causing it, but from my experience the effect of the bug is not permanent.
- I need to check this crow mauler bug too! Some enemy souls can be used as an armor. They are actually pretty useful. I recommend checking it out!
