I'm afraid Yvette can still break the game.
Reproduction steps from my remote save:

First offer her Kristina's medallion as a gift before knowing who she is.
Talk to her again and ask "Where are you from?"
This unlocks probably a redundant dialogue option "You friend of Kristina from Paris?" which ...

First time in London and talking to Yvette in the bar.
Dialogue option "Regarding the task..." gives "IDRef did not find SRCE!" error.
My remote save is at the location.

If I get a pop-up window during a dialogue e.g. "You've got prices from London.", then dialogue options are no longer selectable using a mouse, only keyboard shortcuts works.

No error during business hours. My cloud save is at the location.

Not working in my game, here is video to demonstrate it https://www.youtube.com/watch?v=pNEh_DuY6EM First selling separately and getting fully paid, then reload -> sell everything at once, and i only get contract money.

I don't know whether this is bug or not, but NPC Trader named John has been immobile for weeks in the Øresund strait. I attached my save file, in case someone is able to help him.

I've noticed that if I sell more units than what contract dictates, then I'm not getting paid for leftover units.
e.g. If a contract is 10 units, and I sell 25 at once, then I'm not getting paid for for 15 units. Have to first sell 10, then the rest. I must have lost thousands before I noticed this.
