So I saw a list of version exclusives for SM. It doesn't contain Pokemon leaked from the datamine so I figured it was okay to post here.
EDIT: Why is the spoiler box open on both show and hide???
Take the left path all the way in the big room and you should find an entrance to another room with several rows of tombstones. You need to use the key on the second one from the left in the top row.
He's (actually he, although the quest says she) in the top right of the biggest part of Vejyr with all the lava pillars. Near here is where you should find him:
That bug is known about; it's been reported several times in the thread and in the known bugs list of the OP it also says that every bug in the intro scene is known.
For the Omanyte puzzle, you have to talk to the four Bidoof on the leftmost side of the room in order from top to bottom.
@OpalWardMusicFan: Larvesta isn't currently available. I'm not sure about Eevee but I don't believe it is either. I know there's a Water Stone but I can't remember where to find one, sorry x . x
For a time after episode 1 people got to submit their own trainers for Desolation. I don't remember Ame making one (I think she doesn't play much of fangames outside of developing Reborn), but it could be a reference to her . o .
If you've activated the event in a house in Addenfall with Ava (trying not to spoil in case you haven't), it'll be locked until that part of the story is done. If you haven't, I don't think it should be locked.
This is yesterday, but after I made the "Metapod met a pod of Metapod" status I googled it to see if anyone else had thought of it before me. Then I learned there's an entire album of songs about Metapod from an artist called "Metapodestroyer".
According to Serebii, there was a stream earlier that showed early gameplay of SM and went to Ilima's trial. Apparently there are 7 trials. I'm not sure if that means 7 trials for the whole game, 7 trials for each island, or 7 trials just for Ilima.
It's further up. The locked house near the peak of the mountain where Tristan found you. There's currently no way to get into that locked ranger outpost.
Ame said those who gave the ring to Blake will be able to get the Shiny Charm later on when asked in the "We Make Pokemon Reborn. Ask Us Anything" thread.
(just saw your edit) Yeah, you can PM me the save file. I can actually do it as early as the boat scene if you want. Also if you want it to be a certain nature I can do that too.
