Do you mean that you get stuck during movement or that you can't interact with any characters? Either way, I may need to see the save file as I can't replicate the bug at the moment.
The characters move on their own during the scene. Once they reach the next person they're supposed to talk to the game stops working. No dialogue boxes and it does not allow movement. However the sprites in the background are still animated, so it is not freezing.
How do I send you the save files? I'm running it on mac.
