Well if you don't mind I found another oddity... when you hover over a pokemon you see a tooltip that give infos, this tooltip include a "GameVersion: " info, here is the thing:
Look at this Ivysaur 002 - HERBIZARRE - 5D3D.pk2, import it on a GSC blank file or non-VC GSC file, hover over it and you see GameVersion: RBY which is normal.
Now import the same Ivysaur on a VC GSC file, hover over it and you see GameVersion: GS, also saying it's born from an egg (which is possible but still it's odd).
The move Vine Whip is the culprit here, if you remove it, GameVersion say RBY. (I upload a sav.dat again it's a VC Crystal save file if you need, in this save file you can see the Ivysaur don't have Vine Whip and is considered coming from RBY, give it Vine Whip and you will see GameVersion change to GS).
Should I keep using this thread for anything I found or should I do a new thread every time?
