Jeff used to go on and on about how annoying it was
he did a very good amount of it, i remember testing it in the dev server a very long time ago
he would go on and on about how much time went into doing one potentially small thing
i do not blame him or anyone else for not finishing it because it does not look easy at all to put your mind towards so many lines of code for a small result, especially with a mode as hefty as blitzkreig
