On the other hand, you must take things in the Character Builder with a grain of salt because sometimes there are errors and they may not get corrected for a month or two (or possibly longer). On the other, other hand (the third hand?) those items get noted in the Character Builder FAQ.
They do? I'll have to go look.
I know of about 6 or so bugs in Character Builder that although reported, never seem to get fixed.
But, they seem to have no problem adding new functionality like putting melee and ranged basic attacks onto the power sheets (which doesn't really buy much for anyone).
The main problem I have seen is that some new feats do not modify anything. The PC acquires the new feat and the character sheet does not change. This does not happen for most feats, but its fairly annoying when it happens because the player has to pencil in the change, sometimes in several places (that is if the player notices it, not all players are math geeky enough to check all of their numbers). There are also bugs where feats from the splat books are not in the list. Problems where campaign settings change with new updates, etc.
