This is a bizarre glitch. I've unlocked Wart's Sword, and now every character above level ten automatically enters with the sword equipped...even in playsets where it shouldn't exist outside of Toy Box.
Granted, it's easily unequipped, but still, it's just weird, and troublesome since there are times where i completely forget about it, and when I go to attack the character does little nudge forward instead of attacking before I unequip it.
Oh yeah, I'm also on the PS3 version. At this point is anyone even surprised?
