Cuba (or Mexico if you prefer) is at the start. Most of the movie takes place in suburban America focusing on Holbrook, Munn and Tremblay's characters along with the soldiers Holbrook hooks up with.
There is a cartel involved in the opening in the Cuba scene I read. I don't recall any mention of a baseball dugout, but who knows. The alleged Mexico setting, a dugout and the claim that the character is no longer autistic are the only changes I see from the script I read or the leaked bullet points which have been out for months.
I'd like to give this claim the benefit of the doubt but I frankly don't buy that there is a 'survey' of the script at all, let alone that that would be used on random sites on the Internet to try and make changes to a film in progress. Further, those exact bullet points have leaked before. And his name is not Robbie (at least it wasn't in the script I read), but it has been listed as such before in past leaks from fans.
Of course that's all very hypocritical coming from me, another rando on the Internet who claims to have read the script. But hey, it is what it is.
