So, there is by all means not gamebreaking just slightly annoying bug where Her right arm will have different colour from the body and glow a little. It's easily reproducable for me by either loading new characters (not all of them) or if I just keep randomising, usually one in three girls has said issue. Arm can get bugged in either position (back, on legs, on his legs etc.), however, to get it unbugged, you have to set her right arm to 'back' if it has bugged in either position apart from 'back'. Then it will unbug and you can set it back to where it was without any issues, however, after you switch from 'back' to any other position, resetting it to 'back' will have the bug on it again. The one you can't remove unless you pick different character. If arm bugs in 'back' position, you can change to any other position and it will be okay, but you won't be able to set it to 'back', it will always be bugged there.
