Thiev: With Shadowkeeper changing HP is not enough, you also need to change character status - untick "dead".
Drelmanes: After doing this, the character's avatar colors are back (Like if he/she were alive) , but the character's body is nowhere to be found, and I can't order he/she to move (Or do any other thing). It seems that it's only resurrecting his/her avatar.
yeah same here, didn't find a work around so went ahead and tested the cheat code and it works fine.
from the link i pasted earlier
1) edit baldur.ini and under program options add "Debug Mode=1" without the quotation marks
2) press CTRL+space
3) in the box on bottom of the screen type CLUAConsole:EnableCheatKeys() (you can copy/paste this so no need to type it in manually)
4) press CTRL+space again
5) cursor over dead character and CTRL+R
and voila, alive and kicking again ;)
