My version actually seems to be running fine at the moment, although I haven't gotten very far with it yet.
In regards to the LP I was talking about, would people be interested in seeing a particular alignment-based run (Good, Neutral or Evil)? Assuming anyone has any interest, obviously.
Manual indicates it drops in the usual way it did in BG1 (i.e. not much unless you start stealing from or attacking people). Recruiting Viconia and Dorn will also drop rep by a couple of points. Really though, if it bothers you can just use Shadow Keeper to keep it at the preferred level which does work with the enhanced edition, although it does require more of a circuitous route.
