There's a weird quirk that my osu! gained in last few days. I don't know if it's related to losing my Supporter status, but it started shortly after that (so, just in case that it can be related, I find it worth to mention).
http://puu.sh/mwtPE/97fb729393.jpgGetting to the point: My osu! is set to play random song, instead of the "osu! music theme". This works fine, until I go into Play --> Solo. It should keep playing the song that I heard while being in Main Menu, then focus on it after going to solo, but it often doesn't.
Instead, it shows me the top of the list and switches focus to the very first thing (which for me is still unmapped .mp3 file), just like it does after full processing of the songs.
I tried to close and open osu! few times in row just now, but I could reproduce it that way only twice, that is: (I) after opening an osu! by executing newly downloaded beatmap. For some reason it had Unknown status, which got quickly refreshed to Ranked, but after closing osu! and opening it again, I saw (part of?) full processing when I entered Solo mode. (II) I just closed osu! and re-opened it after some time, also full beatmap processing.
(I) can be unrelated though, as it happens even without opening osu! through newly downloaded song (with normal osu! launching)). Nevertheless, while playing "my normal way" (osu! is opened for many hours, even if it's minimized, but sometimes I close it and open again later), I happen to have it quite often.
My guesses are not always accurate, but I usually sit for some time in Main Menu after launching osu!. Sometimes it's few seconds, sometimes few minutes, but it happened to me trice in last 24 hours that I entered Solo mode almost instantly after opening the game and it overlapped with the strange behaviour that I mentioned above. What I saw was a Full Processing of my beatmaps. Maybe all this jumping to the top of the songs list after entering Solo mode is in reality a result of full beatmaps processing, that occurs in hidden after I start osu!, so it's not visible from Main Menu?
And if it's because of game implicitly processing maps immediately after launching it, to speed things up and not "annoy" the players later on, why it still jumps to the first song on the beatmaps list? This is even more bothersome for me (me is not equal all players ofc.^^) than random beatmaps processing, because I often open osu! and hear a very nice song, which I got interest in and a willingness to play it. So, I instinctively go into Solo mode a moment later, to check the beatmap and.... I either get focused on the very top of the beatmap list or I see the end of full processing... and the song "is gone", as I still don't know most of songs in osu! to find it myself
-------------------------------------------
One more thing about full processing. Unmapped songs are available from Edit mode, but unavailable from Solo mode. However, after full processing in Solo mode, you can get focused on unmapped .mp3 file (that happens, for example, in my case). I don't know how this inaccessibility of the .mp3 files in Solo mode works, but even though you get "focused" on it, the song is like invisible for you (check image link above). You can't use arrows to move to the other songs, like you normally could, but rolling a random song (or F2) still works. Shift+F2 don't work then and you can't go back to the .mp3 file.
It looks like kind of unexpected behaviour for me, as you can access the file that have no beatmap related to it, so it shouldn't be accessible from playing mode.
Sorry for a wall of text, but I hope that any of these words will be helpful in further improvement of the game
