Because of
a bug in the EE game engine the option provided by the "Additional Shadow Thieves Content" component to betray Edwin to the Cowled Wizards doesn't work as intended in BG2:EE and EET.
The following zip file contains a fix for this issue:
questpack-v35-patch-thieves.zipIt is compatible with Quest Pack v3.5. To apply the fix:
- Unpack Quest Pack v3.5 to the game folder.
- Unpack the zip file of the fix to the game folder. Confirm to overwrite a single mod file when asked.
- Install the mod.
This fix is not needed for original BG2 or BGT.
