So far, I've gotten up to Vanguard (beginning of Chronicle 3) and here's what I've found so far:
- Marise's status cure spell Divine Puralis seems to remove postive status effects, too. I don't really know why, I checked and it's not supposed to do this, but I've had it happen several times that I cast Regen on a character with a status effect in one turn, cured her in the next and Regen was gone.
- In the second area, the plateaus, you can pass the first Fiereste barrier from the other side before it's removed, you just can't go back then.
- Vanguard is pretty empty (the only map where you can do something is the shop) and the two shopkeepers look alike and have the same name.
- No idea if that's just me, but the cursor lags badly in all Vanguard maps except for the entrace.
- During the beginning cutscene of Chronicle 3, in the Vanguard hotel, Ellington seems to teleport instead if moving. Probably because of the lag.
- In the shopping menu, Ellington has no walk graphic - makes sense since he can't equip anything anyway, but it looks weird.
Reached the end of the playable game now, here's the rest:
- If you go to the tent where Roselle and Marise rest on the plains before seeing both scenes, you end up on the screen without the cursor or any means to exit.
- The Vengeance accessory doesn't work, or at least not when Violette and Ellington are the only people in the party.
- Just about every treasure pouch, except for the two that gives tomes, either give no item at all or a completely different item.
- A lot of the treasure puches are visible without activating the search option. There's only one pouch I've found that requires this option.
- Minor error here: Violette and Ellington mention a tree blocking the way (which I remember from the 2006 demo), but the corresponding scene with Roselle and Marise has been changed to talk about tracks.
- During the second fight with the Mud Guardians, the one with Violette, you still get Roselle's and Marise's dialog and the battle stops after some turns.
- In the scene after the Mud Guardian fight, the top of Roselle's head starts moving towards Violette and disappears.
- After this scene, Roselle (with complete head) and the key are still visible - actually I think it's an earlier Roselle, she's standing at a different spot.
- The skill Divine Halolis doesn't remove status changes, but attacks an enemy for pretty good damage.
- Primus has an empty skill (no name showing up when he uses it) that works like a normal attack.
- Primus has a healing skill called Chocolate (probably the item) which he uses a lot to heal 300 HP. The fight is pretty much impossible like that.
- Primus doesn't use his ultimate skill anymore, the one where he gave three turns of warning and you had to defend at the end.
- The lesson after the Primus fight doesn't display, it's just a black screen and the characters talking about whatever the book should say here.
- The next area, the Sere Sea, doesn't work at all. You can only enter one screen with no battles and no exit except to the world map. The only thing you can do here is to click on a glowing stone in the middle, which starts a timer of about 10 seconds and when it reaches zero, a textbox appears with stuff like "Battle", "Character Remark", etc.
And this is where the game ends, so to say, since there's nothing more to be found here. Hope that helped!
