I played through the map again on version 1.0.5, and here are a couple more questions:
1. The Necromancer's castle, the one you buy, cannot be entered without the "Portal to Town" spell. This was also the case in previous versions of the map. Of course, it's a very minor bug, but it exists.
2. When you move to the island where the Tear of Ashi is located, it can no longer be picked up.
Otherwise, thank you to the author for improving the map and for paying attention to feedback.
