I just tested and singled out this mod to most definitely accidentally include "Enable Custom Music" custom rule setting. yes. hope it gets removed!

I tried having my usual mods + this, boot up the game, and custom rules starts at (1).

Then I turned it off, exited, re-boot. game still remembers the other resource packs & mods I have active, but no more "custom rule" for "enable custom music" at the start.

also, Quartz Armor and Heavy Glass Armor doesn't seem to have a sprite change, when picking them up from the base look. everything else works wonderfully though. Thank you for the mod, this is a fine alternative to "Bikini Armor" tribute mod!

when starting to load this mod, the game gives a warning of "this mod alters the beatmap, so achievements will be disabled." when I check the custom rules active, it also coincidentally says there is "1" after enabling this. It says "Enable custom music being checked", which is one of the vanilla, from-game gameplay options. Maybe it got inadvertently saved for some reason.

I don't mind it much though since I play with a lot of mods and never could submit to the leaderboards anyways, but yeah. would be worth looking into!

Is Klarinetta not female to you?

May I ask why you made this?
