Worms wont eat cabbage!

[Gablak]

Worms dont eat cabbage leaves or cabbage heads. I guess this is a bug since they eat pumpkin flesh.

Please fix.

Cabbage leaves do not count as "any plant", and my assumption is that worm-food uses that item category.

Try making some Lean Rabbit and see what ingredients qualify for "Any Plant".
Or read the wiki article I wrote based on doing just that.

I think it's a bit of an oversight myself. There's no reason worms shouldn't eat these things. Cotton should be the only thing from farming they shouldn't eat.
