bullshit, the patch is needed because in the game Jason's parents die and he moves in with Diana. And just choosing how he addresses her is not “patch are no longer needed”.
It is just a script edit. The script is from a pervious version, which is why you get the error, so it wont work until this person updates it to 0.60. If you look you can see "Last edited: Aug 3, 2024", so always check the last edit of a mod post before downloading.
Please update your mod.
The reason why the patch doesn't work anymore is because the variable 'jason_rel' that deckmaster mentioned is define manually by the player while playing the game. There's a scene where you're ask how you want jason to call diana and derreck. In addition, there is now all the intro where we are presented with the death of jason's parents and how diana and derreck welcome him in their house. After that there is several lines at different points in the intro where jason's adjustment to his new home is discussed.This part is becoming pretty much unplayable saying 'jason_rel' is not defined all the time. I checked the variable viewer and it just isn't there. Closest is 'jason_points' which in my case = 2
So maybe you are right M0narh and we need a new patch. But given the new code of the game it would probably mean rewrite the intro of the game. Now, i'm not a modder but i have noticed that modder tend to avoid modifying the story. So rewriting a whole intro seems far-fetched. You might as well play the patchless version and make jason call diana, mom, it would save yourself a very probable disappointment. Just saying...
