Recently, I got this glitch to happen where I am playing as both the main character and the co-op player, but I am only using one controller, which is controlling both of them. They are using the same input, and were the same character until I accidentally disconnected and switched the character, then reconnected. I was messing around with two controllers in the Jedi Temple level, and then I believe I disconnected player one. I then had to leave temporarily, but left the game running. When I came back, the game had gone idle and my controllers had turned off. I picked up the Player One controller, and reconnected it. I believe it turned into Player Two, but I may be wrong. When I tried to pause, it reconnected Player One onto the Player One controller, which Player Two was on, allowing me to control both of them at the same time. When I exited the level, I still had control of both players, but I then lost control of Player One, and I don't know why. I am currently trying to get this to happen again in the Darth Vader level by hovering over on one of the rocks as Jango Fett, but I've gotten no results yet. Does anyone have an explanation?

(I have footage of me controlling both, but not of it originally happening, if you need it).
