I'm not even going into a game so it's not #2, I'm just on the random generator menu and typing in (even tried copying and pasting in) the name AstronomicBoozes and setting the settings to:
Size: 8192Towns: ManyWilderness POI: DefaultRivers: DefaultCraters: DefaultCracks: DefaultLakes: DefaultPlains: 8Hills: 2Mountains: 1
Random:0
The click "Generate World" and compare it to what I see on your google drive for that map. About the only thing that is identical is the biome layout so I know I have the size and biome name correct. I'm wondering if it's one of the other settings was different when it was generated? Like I mentioned you don't have a value for Random specified so I'm not sure what that should be other than 0.
No worries if you don't have time, it's not the end of the world. Just wanted to make sure it was something I was doing so if other people were using your seeds they wouldn't have similar issues.
FYI I did also eventually start a game and got the map I expected, just not the one you show for that seed/size/settings.
