For whatever reason my entire map has loaded after being reset for a couple days. I primarily play online multiplayer. This happened a little while after defeating plantera. It’s a really cool glitch, and is frankly quite helpful. But, it is very confusing. I don’t know what’s up with the black bars, and when I explore an area the black bars disappear and it looks normal. Also, I can use my cursor to see things you could normally find on the map (pots, life fruits, chests, etc.)
