I've narrowed this down a bit. I started a game of BG 2 from my unmodded backup, and speedplayed to the point where I got access to ranged weapons (shortbow for Imoen). I did my best to replicate the penalty giving situations in Chateau Irenicus aaaannnndddd.... the penalties are minor at best here. Since I'm playing BG 1 on the BG 2 engine with Big World, this leads me to believe a mod is to blame. Now if I could only figure out which one. I have read through the tweak/fix/other pack readmes, but I haven't found anything that could cause this so far. Is there a mod that changes around ranged attacks in big world? Maybe some sort of bug is to blame.

Edit: I went and tried to replicate it again via Big World Baldur's Gate 2 and I got no apparent penalties when shooting with Minsc, much less the -20 caliber ones I find in Big World Baldur's Gate 1. Since they're on the same game engine on this mod, and should have the same fixes and such applied to them, how the hell is this happening? I am very confused.

That's not what's going on there though. When I have four predominantly ranged characters bundled up in the back, with the two tanks keeping the enemies there, and the archers fire, I see numbers like '9-17=-8'.

Thanks. Trying that now. And Reinstalling it all, just to make sure.
Edit: It doesn't work. I have broken my install. This weekend, I shall redo the whole thing, and make sure not to include those two mods.

It says something like "CruLeTablesEx::Init<>:*string of letters*.2DA not found. Did you install the required Weidu Components?"
Repeated 3 times, each time with a different string of letters. I cannot copypaste from the CMD, and it goes away quite fast.
Btw: When messing with the BP-Balancer setup, I got a few errors.

Well, now I have done all that (uninstalled biffing, ran the setups and uninstalled the problematic parts and reinstalled biffing). Lets see if this fixed anything.
Edit: Oh glorious day!.... Everytime I run TobExLoader, it crashes. There are three error messages, claiming lost files, and then it tries to run anyway, but crashes.
