OpenComputers adds its own version of End Stone (don't know why really) and registers that and the vanilla end stone under the ore dictionary registration "oc:stoneEndstone" but the Oredictionificator refuses to let me enter the colon into the filter GUI. I can copy/paste "oc:stoneEndstone" but it still gets refused.

I don't think the Oredictionificator really should worry about whether or not a registration name is valid and leave that to Forge.

No you can't put a * in the Oredictionificator.

End Stone in the ore dictionary is "endstone" while oc:stoneEndstone looks like the item name call for things like the /give command.

Does the wildcard * work with the Oredictionificator? If so, "*ndstone" might give you what you want.

Yeah the oredictionificator doesn't work. I tried itemSilicon and it wouldn't accept that either.

Still doesn't work in 9.2.0.292

As seen in #3707, the Oredictionificator only works with certain oreDictionary flags for balance purposes.

I can't even convert wood planks. What can I convert?

Probably ores, at least the common ones. same for ingots, and maybe dusts.

I don't think i have ever actually used the Oredictionificator.
