Problem Details:
Despite choosing the "ignore all beatmap skins" in skin option menu, the slider body color and slider border is not ignoring custom beatmap skin unless manually unchecking and rechecking "ignore beatmap skin" in visual settings and restarting the song.
This can be a problem when playing in multiplayer rooms and you get other slider colors different from your skin.

edit: This is a major problem for Hidden players like myself.
