Due to a server issue, I was kicked out of the match, but ended up with an abandonment penalty, and even though I was outside of the demotion protection range, I was demoted.
@t_ayumu_789 Yeah, the issue is that when the server crashes, it usually assumes players had "left" since they're no longer connected to the server. It makes no real sense, so unless things get changed to where we're not blamed for things outside our control, it will continue to be an issue.
