I'm not positive if this is an issue with cutting edge or just a freak error that occurred (I apologize if it's just the latter). And this is probably pointless to post about since it's I guess self-fixable in the end. But normally the game auto-updates before actually starting, and this time it didn't, even though the main menu said there was a new version once it started up. And when it booted up, all my settings were defaulted and I wasn't even logged in, even though I've always had it saved to keep me logged in. I thought logging in and updating myself would fix it, but it didn't. I just decided to re-set all my settings how I liked it and continued on.
I started playing a multiplayer game and once it came to my turn to pick a song, I went into the song select and it suddenly started maintenance. Except that it froze part way and I didn't want to keep the other guys waiting, so I x'd out of the maintenance popup and suddenly everything got extremely laggy. I decided to restart my game, and all my settings defaulted again. So that annoyed me quite a bit and I'm still not sure why it did that.
I was able to replicate the maintenance popup, but I let it run through longer this time to finish (even though the game was already fully updated, so I'm not sure why it would even need to do this).
It also seems to have caused all the beatmaps to become set as "unplayed".
