Get zombies to drop perk books

[voxlltv]

I want zombies to start dropping perk books. Seems like this should be my code for my modlet for loot.xml, but I don't think it's working:

<append xpath="/lootcontainers/lootcontainer[@id='70']">
   <item group='perkBooks' prob='0.75'/>
</append>

<append xpath="/lootcontainers/lootcontainer[@id='71']">
   <item group='perkBooks' prob='0.75'/>
</append>

What am I doing wrong?

Actually... I was assuming 0.75 was 75%, but I see other items in the EntityLootContainerRegular have a `prob` of 10 or 13, so that's probably why I'm not seeing the books drop. I'm going to try altering that number.

Yeah I changed the prob to 13 and 2 perk books dropped right away.
