I seem to remember having stumbled across a couple of sizes of beam in the CC that had something wrong with them. I don't recall if that's one of the ones we noticed - it's been a while since it happened, and they were sizes we don't use often. Fortunately, it only caused some minor confusion for us, and the issues were found before anything was designed incorrectly as a result.
I think we fixed the specific ones we had bumbled across in our custom CC family, but we never did a comprehensive check of the CC table. So there may be more lurking in there somewhere.
