Nope, nope, as I remember, all the answers worked well for the quest. (Our Fargus used to ADD new bugs, not to correct the original ones )
Behold the wonder of readme files
The "party treasure" bug is one of the Eddie bugs that Baldurdash fixes. The same readme also gives a fix for stalled Nether Scroll quests, which is below.
Quit
BG2. Edit BALDUR.INI in the
BG2 folder (Notepad works for this) and put the line
Debug Mode=1
under the [Program Options] line. Run
BG2. Load the savegame. Press Ctrl-Space for a console. Put the pointer over Edwin so that his circle shimmers, then type EXACTLY into the console:
CLUAConsole:SetGlobal("ScrollStudy","LOCALS",1)
and press Enter. This should set the variable properly. Save the game (it's recommended to use a new save slot in case something went wrong.) Quit
BG2 and edit BALDUR.INI to remove the line that was just added. Then rerun
BG2 and load the save and play normally.
