Okay since some people are calling my claim about my worms eating bs. Here's a screenshot plus extra information.
I've put my worms inside a wooven basket. The pattern I used was:
wpw
pwp
wpw
w = worm
p = plant
The plants I've used where 2%-3% pure Blackberries (lead) and 2%-3% pure Wild Garlic (sulphur). Both wooven baskets I've setup had their worms eating.
Best worm I've got after the first cycle is Salt:25.02 Mercury:25.07 Sulhur:23.74 Lead:26.16
I hope this information helps out! I have setup my baskets again and see what happens tommorow. If it worked again tommorow I'm guessing all it took was a server side fix, which makes sense.
p.s. I'm on the Roanoke server.
