Sometimes, I get an error where Osu completely freezes. This only seems to happen on certain beatmaps. So far, I've experienced it on Classic Pursuit by cYsmix, Moonlight Sonata by cYsmix, and Surrender the Throne by Krewella. For the first few seconds, I can play the song and click circles like normal. Then, the screen suddenly stops. I cannot move the mouse at all and it's just completely stuck. However, I can still hear the music going. I try hitting various mouse keys and clicking, though nothing happens. The only way I found to get out of the glitch was to restart my computer and close out of Osu.
