What do you mean about wrong? You soft lock yourself on the potion making because there is NO SAVE OPTION when inside the university, if Damien help you in this part there is no problem. But if not, I don't know about that anymore. I'll try to post the potions formula here. If that's what you ask.
The way you can save again in the game within transitional days in the university was you going back to the ship so the UI shows up again so you can save. You can exit the university at end of the classes.
But for now, I can't give the info because I restarted my whole game and I am not yet in the University as of the moment.
