Soft Resetting List For Shinies??

[EeveeBailey]

Hey, we all make mistake, so don't feel too awful about that mate. Now that you have that knowledge and more, you can shiny hunt all the Legendary Pokemon more efficiently now, so rejoice!!

Hurrah! Knowledge is power! And knowing is half the battle ~
I have been around for..... I want to say two plus years... I don't know time flies... but this thread is the first time I have heard of the auto-save feature. Was that added recently or awhile ago?

The autosave feature has been a thing since version 1.2.0 (a little over a year ago), but it has to be manually turned on and given a duration.  It triggers on a "map change" (i.e. entering/leaving a building, going between routes, etc.), which is how it can be used for Urayne...

Spoiler

.... The game considers the shift in the cutscene from Urayne's flashback in Epsilon to present-day Championship arena as a map change, which triggers the autosave to save when it transitions there (if you wait long enough that is).

As for Garlikid...

Spoiler

Yes, you can check the nickname screen when he officially joins your party after the Larkspur battle.  However, the faster/more efficient way is to have a slot open in your party so that he joins before the Larkspur battle.  Save in front of the table just before reclaiming your bag/items, and he'll join once you do.  You're not doing anything "wrong" per se, but using this method, you can SR here a lot faster since you won't have to fight Larkspur and listen to Garlikid's monologue each time.
