Why does this always happen to me? So annoying. Anyway, in the old download, Buffy was supposed to equip Crossbows and while she could, the weapon would never level up. That's been fixed now, so if you want, here's a new download if you really wanted to equip her with a crossbow.
There was an issue with Matt's equipment, too. So yet another download has been added. Also, there was an annoying error that happened when you tried to scan an enemy after one's been killed. Hopefully that's also been fixed.
Luckily, you don't have to start over. Still, sorry for the inconveniences!
