False alarm! It was that lurking divide by zero exception. Luckily, Karl was running the server in debug mode and it looks like we've caught it. I've given him a quick report and he should be able to hunt it down tomorrow. I've restarted the server for now.
And the update which I thought this was will also be tomorrow. This won't be the item update, I'm sorry to say: the current item system is more than haphazard (as I'm sure y'all can tell), and we're working hard at the moment to build a very robust system which will last us. I think y'all will appreciate the delay when we do finish, though, because we've got some pretty sweet things in the works!
Tomorrow's update, however, will be another step toward an economy: the Bazaar and gold. I don't want to give details that turn out to be incorrect, so I'll leave the full reveal to Karl for when he releases tomorrow morning.
