Forked.
Silver has been away from the game, and the devs changed the way information is passed. This change made the script unusable, and Silver is nowhere to be found — and we love Silver.
This fork changes two lines of code:
Change line 810 to:
item.type = capitalizeFirstLetter(itemGlobData.itemtype);
Change line 1079 to:
var ammoTypes = ['32ammo', '35ammo', '357ammo', '38ammo', '40ammo', '45ammo', '50ammo', '55ammo', '20gaugeammo', '16gaugeammo', '12gaugeammo', '10gaugeammo', 'grenadeammo', 'heavygrenadeammo', '55rifleammo', '75rifleammo', '9rifleammo', '127rifleammo', '14rifleammo', 'fuelammo'];
Thanks to TectonicStupidity for posting the fix on the game's forum.
