Got it. That was just what I was looking for in clarification. I will probably read the BG2 manuals, just as a basic reminder as regards the foundation of the rules, but I planned on basing decisions on what I would do based on in game descriptions and mod readmes. I think I may have a decent idea of what components in what readmes should apply as the rule(s) to follow for the modified game I built as I read every readme of every installed mod, whether I installed a particular component or not, and probably every part of the Big World Project v14 pdf that dealt with the installed mods and components, mods and components that I didn't install but that could/would have conflicted, a ton of threads about the various mods, and about mod order and installation.
And when I have no freaking idea why something is happening, I'll come here and to the gameplay subforum and prod people with oratorical sticks, put taps in the holes, and collect the answers that will surely flow freely.
Thanks for such a quick response and have a good (input the present and immediately upcoming position of the earth relative to the sun and moon in your area).
