Recipe: Process Corpse Into Propane

[AlximikXD]

Issue: The possibility of processing the corpse into propane without the propane canister itself

Solution: Add an empty propane tank to the Process Corpse Into Propane recipe

Planned. The propane recipe was a drop-in replacement for the cannibalism recipes.
Intend to "flesh" out this later.
