Problem Details: So recently I've noticed that some of my beat maps have been removed from my collection folders without my doing. Some of them I just had to look up and re-add them while others I couldn't look up in OSU, but they still showed up in my OSU songs folder, however they were corrupt and I had to re-download them. Is there anything I could have done to cause this? Or was it possibly a bug from a recent update, or maybe just bad luck? I also have 48k beat maps in my library, maybe that's too much for OSU to handle all the time?
