The events for Lauren and Sarah majorly changed in 14.14 and the process for charming Lauren is a bit different. You cannot charm her before the meetings on the landing, but in practice it is a lot easier in the events where you do the dating sort of events like work out in the gym with her or go to the pool. I just tried and get the charm popup at the pool with her.
You should still get the simple popups like 'it fizzles' or some variations before the landing scenes. Again I just tried and get various fizzle messages
Can you post your save game where you do not see a message/popup? I cannot locate any situation, so it would be useful to try to work out the issue
Sorry, can't send you my save but I try to start new save and get to this point of the game. And I wasn't talking about charming in Sarah's room. I was talking about random event with Lauren at Gate's mantion. This random events don't have pop up. You can charm Lauren with this random events and now I know that there is better way to charm her, but if you do old version of Lauren charm with this random events then you still don't know if it worked. I mostly played with walkthough and there was pointed old version of Lauren charm. This is why i did old version of Lauren charm with random event. Then can you update this part of walkthrough?
Quote from the walkthrough in chapter 4 at apprentice path- "Now pay a visit to Sir Ronald Gates and ask him why is the Mansion locked at night. To be able to ask this question you have to have tried to enter the Mansion at night. After Sir Roland answers immediately charm Lauren. This isn't enough, you'll need to charm her twice more. Fool around the house and pass through the Entry Hall frequently, you'll meet Lauren there randomly. It can take a lot of time to actually meet Lauren twice, so be patient or come back when you have time."
