It was not obvious to me that, when leveling up, unspent skill points would be saved for the next level. I figured it out only when I realized that you always got 6 skill points/level but at some point another level in a skill cost more than 6 skill points... which I think I realized at character level 4 or 5.
I've probably already screwed up any chance at getting one of the in-game NPCs or my PC up to top level in any skill, but I suppose I can create adventurers specifically to go pick the locks on leftover doors in late-game areas.
Do you know exactly what form the fix will take? E.g., will companions that have lost their items have the items restored, or, is the fix only going to prevent items from being lost in future swaps of companions in/out of the party?
