It would be nice to know if you've read this post, looked into the issue, confirmed it's working properly, or even that you give a damn. Some feedback would be awesome as my forager gets really crappy pulls too.
my forager farms n lake, he gets rares often and t30 every now and then with 100 forage. my miner get rares and t30's often with 100 mining. my woodcutter/gardener on the other hand doesnt get anything, t30 wood hardly ever and no veggies at all with 100 wood and 99 garden. its all a crapshoot luck based. all we can do is get as fast kills as we can for more chances and hope it pays off every now and then.
