Rows FC-FJ the object group rows say that you need to subtract 2 from the row # to get the id number.I was trying to match up some of the levels to the objgroup and noticed that it seems as if the number used is the offset number in objgroup.txt.
ex. Crypt 1 A(19), Crypt 2 A(20) have 7,8,9,10 in objgroup.txt.
Using your method this would be 5 to 8 in objgroup or Sewer Shrines, Cave Wells, Crypt caskets, and crypt shrines.
Using the offset number would come up with:
Crypt Caskets, Crypt Shrines, Crypt Chest, Crypt Barrels.
Is it row-2 or the offset number in objgroups.
Just trying to clear the confusion in my mind, Thanx
