I started an unmodded game of the original Baldur's Gate and something strange is happening, at least I think it is strange. If I roll a single class character when the smoke settles after Gorion's scene and you meet up with Imoen she is a level 1 thief.

However if I roll a multi-class, I've tried fighter/mage and cleric/ranger, when you meet up with Imoen she has 1304xp and is a level 2 thief. Is this normal? I was planning to dual class Imoen at level 3 but when the game levels her up she puts points into stealth making a level 3 dual impractical.

As I said this is a completely vanilla game downloaded from gog.com, is this normal?
