I apologize again...it's a bit embarrassing, but at the same time maybe I found a bug in the game. As I see also
Mardrigon had the same error?
As i said I started the game from scratch again. And shortly after starting chapter 1, when I try to go to the gym to talk to Chaterine, the game gives me this error:
I've tried several times to reload, but nothing, always the same error.
Not being good at this sort of thing, I did however notice that it says script.
So i tried closing the game and starting the older version of the game. To be precise PowerVacuum-Chapter_9.
From there I loaded my save from Chapter_11 version and it loaded the game and let me do the gym event with no errors.
After that I saved again and reloaded the save in the Chapter_11 again. I don't know why but in the current version, the first event of Chaterina gym doesn't work. But in the old version yes.
I hope I did the right thing to have posted the error. At last i hope in this way the error will be corrected.
