While you're on it, I've heard that when you set special style (Right) in options it tends to reset to special style (Left) after rebooting the game. I don't use right scratch so I can't confirm it tho.
when you press one special key and then another so that they are both being held, the second press does not register this makes it near to impossible to play some maps where you need to use 2 fingers to play the "scratch" or the special key lane as you can see in the video i made, the key presses don't work if you have your other special key pressed.
Yeah alternating both 8k special keys for non-jackable special lane streams doesn't work as intended. Right now you need to completely release the first special key in order for the second to register which just makes this the same as jacking.
It should be working just like taiko or standard dual maps and it's not.
There are currently ranked charts employing these patterns that can't be played as intended because of this bug. It's game breaking and has apparently been reported for 3 years now, please fix.
