Is it the very bottom crystal of non-2.0 ones in the gallery, by any chance? I want to make myself good transfer save too and this is the only scene I'm missing. I think it was for the 3rd party member who never appeared, i wonder if NG+ will fix it.
No, The only non 2.0 events I don't have unlocked is the caretaker line, which requires certain titles to advance, but I'm not sure what they are.
Out of the 5 2.0 ones, I've only managed to unlock 2 of them.
Oh, and it'll carry over the Guard collecting too.
Edit: Oh yes, the single crystal is for the third character. She's also present in Episode 2. Basically after some time after she becomes available she remembers an incident.
Edit 2 (To prevent double posting):
Porting over EP1 data (I gave up trying to trigger the missing events, if anyone's got a better save, let me know) does the following at a first glance (early game):
Benefits:
- All GC levels are carried over. You don't get any of the GCs though, but when you find them, the levels will be retained, meaning an early boost.
- If you completed the photography job for EP1's MC, her photoshoot is now on the shelf. Can't buy it though.
- All shared areas will have their map data saved between episodes.
- Makiko (The returning Char from EP1) will return with ALL her stats and equipment, right as you left her. This means if you unlocked her memory from EP1, she's missing a blocking skill that she would normally have, and if she was level 99 in EP1...
- It's also a way to get your hands on one of those accessories that randomly boosts sexual desire.
- After finishing the main story, you get to use the EP1 characters and get all your inventory from EP1 again. There is however a catch, all the locks that were in place are still in place, so if you didn't get a level break, they'll still be level capped, and if you didn't break down skills, they'll still be there.
- If you make a save file, you can backport the EP2 data back into Episode 1 (!?)
Bugs:
- All passive skills need to be triggered, even though they're marked as on in the extra menu. Oops?
- If you teleport remembered a map in EP1, you can go back to it, if you do it before the storyline forces a teleport save. This means for example, you could end up at the very bottom of the extra bosses map or in other strange places.
Patchfixes (!?)
- You know the bug where Michael's sword upgrade costs zero after upgrade 11 or so? Porting EP1 data actually locks the figure to 4000SL per level instead of 0. Dunno why, but it happened.
