Ever since the update that added the "circuit using wood" recipe, that one is selected when a machine with "set recipe" enabled is sent the "electronic circuit" signal. There ought to be a separate signal for the wood recipe, and machines should only select the recipe when sent that one signal.

Additionally, it seems there's no recipe signal for "Casting Steel Plates".

The "Processing Unit" signal also causes electromagnetic plants to select the "Processing unit from Pentapod Egg" recipe even when not on Gleba. And while an idea to keep a Pentapod egg farm alive in the Maraxsis trench, fed on tropical fish, is occurring to me, sadly the egg replication recipe only works on Gleba.
