So I saw that the maps were supposed to be fixed so I went to a map we have and i even tried to create a new one of the broken area but it ended up the same. Also, the banners that show up on the map are impossible to read and you have to move around to see parts of the words.
Environment
Java Version, MSI with windows 10, 16 Ram, and i-7 intel core CPU with 64 bit operating system
