Thanks for the explanations.

So, your install may well be f-ed up now

Yes, I've understood that a little while now  

Well, it seems that my installation is evil or something. After I returned the old AR6800 and hobjoia.cre, it started to CTD on each and every area except Candlekeep areas. The cause was again CreatureSize.
I now tried to remove xpmod-reduce 50%. But it's strange that every time I try to uninstall/reinstall something by running the respective setup file, the installation progress will continue after the uninstall/reinstall. So after the component I want to ajust is uninstalled/reinstalled, it starts installing other BWP mods that have been installed already, starting from BGTMusic. Is this a common problem and how can it be fixed?

Mods affecting HOBJOIA.CRE:
00000: /* from game biffs */ ~SETUP-BGT.TP2~ 0 0 // Baldur's Gate Trilogy - Core
00001: /* from game biffs */ ~SETUP-XPMOD.TP2~ 0 1 // Reduce to 50%

I think I have no idea what could be causing this bug. The only thing I remember from this forum was some abnormal item equipped in a slot where it shouldn't be. But that's not the case here.
I attached it but I will still be studying this cre file for errors when I have more time.

The corrupt file was hobjoia.cre, the hobgoblin that is supposed to drop Joia's ring. I'll just remove the actor, since I don't know how to fix it.
