My map, no galaxies on it, no problem, i made a new character, shouldn't have any galaxies explored.

But, no matter where i go, or how many galaxies I explore, when i log out, and then log back in, my map is back to completely blank, except for the galaxy I'm currently in.

every single time. without fail, have tried restarting my system even, just so i could clear that up.

its really irritating.

Tried to use the centering button?

Yeah, centering merely puts the single galaxy im in in the center of a large blank space

Having this issue on another account. Changing layer then returning has corrected it for me. Maybe you tried that.
