I am creating a mod that includes copper and tin, and I found that I am having trouble making my mod compatible with IC2 (It works with Galacticraft). Am I using the ore dictionary wrong, or is there something else I need to do?

Edit: I've tried out my mod and IC2 with Thermal Expansion, a mod with copper and tin, as well as electrum, and it works with both. My mod and IC2 still aren't compatible.

Looks like a bug with IC2, which I would attribute to IC2 not being updated for 1.5.2.

I'm using a 1.5.2 beta for IC2, so that might be a problem.

Probably. Where did you get a 1.5.2 beta, if you don't mind me asking?

They post development updates on this Jenkins. Apparently, they are adding more boat variations in the next update.

Alright, I've reworked my crafting recipes and it seems to work now. It wasn't actually a problem with IC2, but how I had the Itemstacks handled.
