Good news: I've identified the issue causing the world map to completely not function.
Bad news: The problem is that the latest update to RPG maker completely broke the plugin I've been using.
Less-bad news: The plugin creator is aware of the problem and has mentioned that they intend to make an update to make it compatible.
Less-good news: No ETA on said update.

So, what that means for Dragonfall:
1) I'm searching for an alternate plugin that isn't completely broken. If I can find one, I'll be able to push a release more or less as soon as I get it installed.
2) If I can't find a replacement, I can and will continue to work on other aspects of the game, including new maps, story, battles, skills, etc, since none of that is directly dependent on the world map.
Either way, there will continue to be progress and updates. Thanks for you patience.
