Hello!
Sorry, the problem might actually not be here, but this being a recent mod...
So I am running a play through with a lot of planets, so a lot of mods.

I can place the machine (the UI says it comes from here) and it barrels the fluids just fine.
When I try to unbarrel, however, the filled barrel is consumed, but nothing comes out of the machine.

Just wondering if it's known.
I can post the list of all mods, if needed.

To add to the issue, the mod (I believe on purpose) removes all unbarreling recipes from assemblers, so I can't even unbarrel at all (which proves to be an issue with Muluna).

Wait, wrong mod. I see the issue comes from here: https://mods.factorio.com/mod/fct-barreling-machine/discussion/67ec75b2c79ce8829891b8eb

I believe the problem might have been when Rubia is enabled (though that issue also affects the barreling process, if you input a barrel before inputting a fluid), and should be fixed with v1.0.2

This change I forgot to import from the previous iteration of the mod
