So, I have Forestry, and it doesn't have dusts. So I installed Pulver, a mod that adds oredictionary dusts. So I have DustCopper, IngotCopper, i can smelt dust into copper, but i can't crush ore into dust. So why Crusher didn't registered? Tags are fine

Pulver creates these items far too late into the loading cycle, so they are never detected by AA.
