So, about 3 weeks ago when I entered my collections in osu!, I noticed that the number of maps in the collections fell down drastically. What I found out was only maps I had a score on (not all of them) were somehow removed from the collections (they are still playable and can be found among others) and local scores won't show up (only A,S,etc. will show up if I manually select the song) but at the same time the global rankings are always there. It may be seen on the screenshots. It's a bit annoying cause I can't see what maps I've already played unless I go through each of them separately. How can I fix this problem?
