LiquiCrafter does not output multiple items for recipes that give multiple different items

[kutschkem]

In Factorization, the mixer recipes give multiple different items as output (sludge + clean gravel (+ empty bucket)). The LiquiCrafter will only output one of these items (clean gravel). I suppose this is not intended. Maybe output these items directly into the inventory, or have multiple output slots? Of course outputting empty liquid containers does not make sense.
