The bound pickaxe when used in "Beast Mode" in v1.3.0 produces odd behaviour when used with GT Ores, in that they produce odd drops - like Deuterium ore from Iron.

If the answer is "GT is weird" - that's fine, but I thought I should alert you to unexpected behaviour in case it results in incompatibility with other mod ores

Silktouch?

Yeah - is that the issue? I used a ST Tinker's Hammer on them fine
