Regrettably, I didn’t come across any bug like this during any of my testing not the play testers either. It sounds like the characters may have moved too quickly in a previous level and the momentum ‘carried over’ during the scene transition so you ended up what you shouldn’t be. Try restarting and moving slowly and carefully into the starting area of the previous level and see if that helps? Apologies for the inconvenience!
Also re download the latest version of the game in case something went wrong there.
