Hi, I think I've got a pretty big problem in BG2. I started playing the game again after some time and tried to complete the De'Arnise keep quest with jaheira in my party, but totally forgot she was cursed. So I used the rest button a couple of times between battles before realizing that Jaheira was in a pretty bad state, so I did a pretty stupid move and kicked her out of the party hoping that I wouldn't have to worry about that anymore. So here's the problem, after the quest I went back to the big city before discovering a message that told me that Jaheira was dead...
So how bad have I screwed my game ? Can I still resurrect her in any way even if she isn't in my party anymore ?

Thanks in advance.

No, you can't resurrect her. She would have to be in your party, which is impossible at this point. You can try going back to an earlier save.

Okay, thanks a lot ! I don't have any earlier save, Guess I'll have to start a new game...

If you don't want to start over, you could always take a different NPC.

Yeah I was thinking about that, but isn't Jaheira really important in Baldur's gate's plot ? I mean she's one of the first party member and she was here in the first I think, so...

The people who are important to BG's plot are the people you bring with you. Heck, if you want to, you can have less than 3 minutes' interaction with Imoen throughout the whole game.

Jaheira has a lot of sidequest-type stuff going for her, but unless you were dead-set on romancing her or something it's not a major loss. A number of other characters have similar amounts and variety of bonus sidequests.

Okay so I'll continue with other characters then, thanks everyone :)
