We need to clear out bools in PreWorldGen too

[JavidPack]

From forum: "For some reason when i make a new world some bosses i haven't beaten are checked out, the only mod i have that adds bosses is calamity. The first world i made had all the calamity bosses that i had beaten in a different world checked out, and when i made a second world the torch god, blood moon and solar eclipse were checked out."

OnWorldLoad isn't called when generating a world, so data from a previous world loaded will be saved to the new world when that world finishes generating

Measures have been made to resolve this. Reopen if issue persists.
