I did some testing and version 1.4.10.0 and 1.4.10.1 doesn't drop the correct item from challenger mobs. I went back to version 1.4.9.16 and the items do drop properly. Currently the items will drop with missing item textures and I cant seem to craft anything with them. It does seem to have the correct item name.

I am using Forge 1.10.2 - 12.18.3.2281. And this is just using a test world with V-Tweaks, Neat and JEI

Thanks for checking into this.

So this is partially my fault; I rewrote my config parser to be more generalized, but in the process I changed the functionality and forgot to update the config file to reflect this. The new layout is such:

If you want to add an Item/Block with Metadata and Quantity, do:

<modid>:<item>:<meta>*<quantity>, example: minecraft:dye:8*1 adds One Gray Dye

If you want to add an Item/Block with Meta but without Quantity, do:

<modid>:<item>:<metadata>, example: minecraft:dye:15 adds a drop entry consisting of 1 bonemeal

If you want to add an Item/Block without Meta or Quantity, do:

<modid>:<item>, example: minecraft:saddle drops a saddle. That's it. Just a saddle, no special data.

If you want to add an item with quantity but without metadata, you have to include '0' as the Metadata. This is just because it makes my regex parsing much easier and much more efficient, so maybe that was your problem? I haven't implemented an option for `:* in this config I'm afraid. I went and tested this thoroughly and using this layout, it worked for me using other mods.

Hope this helps, next release will have an updated config file clarifying the configs correctly :)

Awesome thank you.
