So, here's the basic story:I make a map, I post it, I rate it 10/10. I wait to see what people think about it. The next day, it's rated 5.5/10 or 7/10. I look to see who rated it down, and it doesn't show any downraters- just the people who rated high. This has only been happening recently, so you won't notice it in my older courses. What is up with this problem?
