The reason why the Gravekeeper is not in the camp in Baldur's Gate 3 is that there are three types of players who can solve it according to their own different situations. After the solution is completed, re-entering the game can solve this problem.
If the tombkeeper cannot be found in the camp, he will need to complete specific tasks after resurrection and meet certain conditions before returning to the camp.
Another reason why this happens is because there are bugs in the game that need to be fixed.
The reason for this situation is that you were summoned after death, so you cannot return to the camp again.
