I have found more bugs in sandbox: You can scroll through all the lip colours on the right to loop back around to the beginning, but you can’t do that on the left, it gets stuck on the first option purple. And if you keep clicking the left button while on purple, you will have to click right button multiple times to get back to the rest of the colours, specifically the amount of times you’ve clicked on the left button.
Also, if a preset adventurer has a different lip colour to the base one, if you try to scroll left with it, it will jump to purple instead of going to the previous colour before the current one.
