It´s insane how the game allows this to happen, this is what i love about it. It´s just so flexible, even if this is a bug, it just shows how everything is just ingame and so maluable.
I know why it’s because umbra can aid you in battle so the game is confused as he can be himself so there’s two versions of him what would happen if he was a normal frame and what would actually happen if umbra was there
