I have 17 explorers 12 of which are fully upgraded to artifact search....and for the last week all they bring back is fishplates or a sandwhich
my 3 lucky explorers are upgraded as well and I haven't had beans or guild coins either...just coal or iron ore.
I know it is all percentages but I was getting bags of snow fairly often but I'm not now, is this a bug or have the percentages been nerfed again?
