I just fc'd 5* map which was "Meaning" on "Tears" difficulty made by Janpai but somehow didn't get the badge, my combo was 349/349 and accuracy was 99.73% so whats the problem here?
The map is 4.99781 stars. So yeah, it's going to be rounded up to 5 on both the website and in game for display purposes, but the medal requires the map to actually be above 5.
