Fumarata: Encountered this when using the final dialogue option for a tongue twister with the singer back stage. She asks the band if they are ready, but no follow up dialogue happens. I let the game run for 30 minutes unpaused, but it did not change states.

The same situation happened when talking to one of the twins while they were trying to break in to Herman's room during the first act. I can pause and unpause but have no control of the character. I also cannot enter the main menu and had to exit the application to fix it.
