I was making a new installation, installed bg2 tweaks followed by SCS and aTweaks and ran into a problem. The improved fiends component from aTweaks threw up an error:
WARNING: minimum_proficiency received illegal arguments: value = 1, proficiency = -1
ERROR: cannot convert PROFICIENCYLONGSWORD or %PROFICIENCYLONGSWORD% to an integer
ERROR: [BALOR01.cre] -> [override] Patching Failed (COPY) (Not_found)
I immediately thought it's because of that bg2tweaks component with the BG1-style weapon profs that I installed, and I was right. After uninstalling it, aTweaks proceeded to install just fine.
I really like the BG1 proficiency system, and want to keep it, so I installed the proficiency tweak after that. And now I'm wondering whether this is gonna cause enemies to have botched proficiencies and get massive penalties and suck as a result of that?
