This is awesome! Believe it or not, I actually never made a full map using the ingame layout itself. The whole overworld is a single scene in the engine, so it makes it hard to have a full view of it without much of the engine UI cluttering it. If you do end up finishing the grid, I'd like to see that too.
I'll look into the issues you mentioned, seems like a tile or two got missplaced.
Also, if you can post a screenshot of your inventory on your most complete playthrough I can tell you if you have everything or not. :)
