Honestly I would love a built in map, even if it didn't show biomes or anything and just let me mark things down on it. I always play using a map from the mapping subnautica page on the wiki because I'm really forgetful and can't remember what place…
Bit of an update. I went on today kind of hoping it had fixed itself but I started about where I was standing when I saved but just fell through the world and ended up where I was before. Endless falling through a void
