Sometimes I run osu from Steam launcher. It might cause the problem. I opened the game with Steam and then I couldn't saw any collections. I tried F5 but only 1 collection appeared and there was only 74 beatmaps. It should be at least 5.000 beatmaps. How can I recover these collections. By the way I didn't lost any beatmap.
