This is the point that I think is escaping many people in this thread. The options aren't as simple as A/A+B in Newcomb.
The map has been stolen. Everything we know about how Time Travel works in this universe indicates that this is a fixed fact that cannot be altered. Who took the map however is an unknown, and while it cannot be 'altered' either, the Effect can in this case precede the Cause. 'Map has been taken' can happen before 'Harry takes map because someone had to' such that B causes A and A leads to B. If Harry doesn't commit to it, B is still true, and so the Map is lost to him. His choices are (Map is Gone, I have it.) or (Map is gone.) The choice 'Map is still here and Hermione lives' is not a valid choice and should be discounted. So, his choices are to benefit or not benefit from the Map being gone.
The interesting question is, if the Twins forgot the Map entirely, how did they remember 'Deligitor Prodi'? Admittedly not perfectly.
if the Twins forgot the Map [...] how did they remember 'Deligitor Prodi'?
Why would the two be linked?
