I've ran mine for 5 days straight before, because I left town.
OMG. I hope you didn't check your log to see what you didn't pickup. I try not to do that cause it usually just makes me sick. While the unique rings stay on the ground I hold in my stash that amazing 1-2 cold damage small charm.
same here, i have well over 1k mf with my merc so i find tons of good stuff...i keep putting off editing my pick up list cuz it always messes up and i have to put it on all my bots (i run multiple)
