In "Say hello to my little friend" the last thing I completed was "Deliver the envelope to the "guy with the bad fashion sense" at the main floor". I still needed to do "Return to Chef Apollonia and tell her everything". If I go to lab B-2 to complete "Dairy quest", I'm sent to Apollonia's main hallway. Entering Quality control soft locks the game. no cutscene is played. Violet is moving between dishes. Apollonia is in a new weight stage. I cannot move or open the menu. I've been able to repeat this glitch.
