... ... Oh my good god. That's just ... ...
scary.
Because, take a note of where the dive warp is on that screen #1. You appear on screen #2 in the same coordinates on the screen! But a Dive Warp operates like a Stair Warp: It uses the warp arrival coordinates! Or at least, it
should! So I can just rearrange the second screen to match the first screen logistically.
By the way, screens like screen #3, you don't need to take a screenshot of. It's just a blank screen with default tiles that's affected by the Dmap's palette. It's not an actual constructed screen. In fact, it's more like Screen 80. (A screen reserved for Item Rooms, a'la the original NES Zelda game.) You can just tell me that screens like that are a "Null Screen." I don't want to trouble you to take a screenshot of a screen like that.

Thank you again though, very much. ^^,
So yeah, if you ever find yourself on that null screen 80, go south if it's from a Cave style Dmap, or North if it's from a Dungeon style Dmap. You can tell which is which by how you can move on the screen. If you automatically move into the middle of the screen 2 spaces, like in the Dam, or Error's Mansion, or the Hotel I believe, it's a Dungeon Style Dmap, and you should go north to escape the screen. If you don't move in 2 spaces like that, it's a Cave Dmap, and you should go south to leave that screen and go back to the original screen you went there from.
