How to reproduce the bug

Check this structure:

The pattern requires birch wood to be transferred from the storage bus side (the left barrel) to the pattern provider side:

But as above shows the level emitter doesn't do anything.

Expected behavior

If the emitter works correctly, it would request a redstone block to be "crafted", which would shown by the crafting monitor (manually request in the screenshot):

Crash log

N/A

that is not what the "Emit redstone to craft item" option does.
what it actually does, is act as a pattern provider with the recipe "Nothing -> Redstone Block", and if you request a redstone block, it will emit a redstone signal until the request is satisfied (ie. the system got a redstone block)

If you want to requst something by sending a redstone signal, you need an export bus with a crafting and a redstone card
