Whenever I try to craft something in an AE2 crafting terminal and it has a game stage (I have the stage unlocked), it doesn't let me craft it.

Crafting the item in a regular crafting table works fine though.

You need to set the stage of the container. (as in, the AE container does not care what stage the player has, it only cares about what has been assigned to it)

What do you mean by that? The item and player have the same stages, so it should work.

Isn't that what determines if it works or not for regular crafting tables?

AE isn't a regular crafting table.

Ah ok. Of course they use their own API, ah well.
