i can confirm i encountered that bug with the map when i looked at https://osu.ppy.sh/b/1007522?m=0 earlier today but now is loading properly. My friends list is also working and I have not seen that bug. Assume it's just a glitch in the matrix.
I can confirm that what is happening in the 2nd screenshot is happening for me as well, seems to fix itself if u reload the page a couple of times but it comes back.
