Thank you very much, kind sir. Now I know how to use the search system better, but I'm still a bit new here (I've been here for a while, but I come in from time to time, when I have time), and of course, seeing a thread of more than 50 pages is a bit hard to start looking at.
So I see that what's wrong here is that the mod version is not compatible with the game version, and that not much has been lost either because then there is no more game until the next version is released. Therefore the error that occurs is that we don't get the
"To be continued" message, basically. That's why having saved the game a little before the moment in which the error pops up, I tried a different order in doing things and the result was the same, because there is nothing else for now.
I hope my post helps more people who have the same problem
Once again, thank you, now we have to wait...
