Issue Description

Placing a non-blank gene sample into an Extra Utilities 2 furnace causes two empty gene samples to be created. One of the gene samples appears, as expected, in the output slot then another unexpectedly shows up in the input slot of the Extra Utilities 2 furnace. The item isn't a ghost item either. You can take it out and it's most certainly there.

What should happen?

The item should only produce a single blank gene sample on completing the smelting process.

What actually happens?

Two items are created, one in the input and one in the output.

Cause of issue?

Since the issue only affects the Extra Utilities 2 furnace, I have a feeling its something to do with either @rwtema's furnace code or @bdew's recipe system not being compatible with that specific furnace.

Ideal fix?

Stop the duplication of blank gene samples appearing by either fixing it on Extra Utilities 2's side or Gendustry's side.

Issue Media

What appears after the furnace process of smelting a gene sample from Gendustry is complete in the Extra Utilities 2 furnace.

The same process as above, but this time done in a regular Minecraft furnace.
