"Original - II"

aa, I understand you now, that's incorrect, it's generated randomly

or rather, you're right in this case

No, I think there's a typo in the rules.
What's the point of marking before the 1st map if the 2nd and 3rd maps will be random with races and templates?
I think the key here should be that the maps aren't generated immediately, and the marking remains valid – the 2nd and 3rd maps, with the already marked races and templates, are generated.
You wouldn't have to mark them again after a restart.
