Storyline Select

So I'm asking this because I don't want to screw up my character. Like if I skip to g2 will it cancel out g1 since they're both in the same chapter?

My elf did g1 and g2 at the same time. o -o

"Skipping to a later part of one chapter (e.g. Chapter 1 is comprised of G1->G3) will make certain rewards unattainable."

I'm assuming this means that yes, it will prevent you from doing G1. That's what I would expect anyway, and was true before this method of skipping it.

Nise Panda's doing both was probably because one was the old version that you can't get anymore...

Of course I haven't actually tried it, nor would I. :x

Well I have two answers, Which is one is right?

I can verify that skipping to G2 no longer prevents you from doing G1 (at least, if you're no further than the first quest):

My character, who had not yet completed Missing Townsfolk, used Select Storyline to skip to G2. Right afterward, she completed Missing Townsfolk (which now ends by sending you to Nao for a rebirth), and got the G1 intro. End result was she had both "The Snowy Hills of Sidhe Sneachta" and "Knight of Light" quests active simultaneously in her Goddess quest tab.

I then tried with an older character who was on revamped "The Snowy Hills of Sidhe Sneachta" and skipped to G2. She also ended up with both "The Snowy Hills of Sidhe Sneachta" and "Knight of Light" active simultaneously.
