Basically, if you want to have an item with a data value over 100, eco creature will ignore it, and will not parse any drops for the creature with the item in question.

For instance:

• '340.22:1-1:3' will drop 1 book with data value 22, 3% of the time.
• '340.207:1-1:3' Doesn't work, and breaks the creature's drop list.

These books in question are tied to Bookworm. I use them to distribute spells from MagicSpells.

I am sure this might effect any custom item added by any plugin, with data values over 100.

See issue #18 on how to specify values above 100.

I will have to take a look at Bookworm to see how this can be done.
