I'm not sure if this is a bug or if I'm just doing something totally wrong but I've recently noticed that when I changed my beatmap's background image and updated the map, the background image would change on the beatmap's website page but not in-game. I've tried deleting the map and re-downloading it but that wont work. Even my friend has experienced this problem so I don't really know what to do.
