• Wight experience penalty reduced slightly, in line with new racial penalty amounts.
• Forest Wight generics are now all unalterable, by player request. Allocate carefully.

The only thing that could break last patch was if you deliberately went in and undid the final point in one talent, then redid it, and even breaking it would not crash the game... but some people prefer a "you can't break it" to a "it won't break unless you go out of your way to break it" experience, even if the latter preserves flexibility.
