Regarding Primeval Brews and Aeonic Weapons.

As our fellow Japanese friends have discovered, there is a line given from the Goblin involved in the Aeonic weapon quest that states that Primeval Brews are bad and not to use them. The Japanese players have taken this to mean that any NM killed when a Primeval Brew is used, will not count towards NMs that need to be killed to obtain Aeonic Weapons.

This line is missing from the North American version of the game. Is this because it is merely flavor text, or was it an omission for a different reason? If there is actual meaning to the warning, why is it not included in the North American version? I can imagine that most NA players who do not communicate with our Japanese friends would be quite upset at wasting 11 million silt.

If you could please clarify if this is flavor text, or if it's a real warning, most of the NA playerbase would greatly appreciate it.
