seems so. We'll probably do soemthing about it soon.

in the meentime, Silver as a weakness would kinda change a fundamental detail of the universe. I'm not sure whether that's a problem or not (mainly because the canon council is in roughly the same state as the DFC) but I personally avoid doing things like that at all costs. I'll get a more definate answer as soon as I can.
