Is this common or did I screw up ItemRules or something?

I ran the bot for a good 10-12 hours while I slept. Usually when I do that I wake up to at least a couple of good items... Today I didn't have anything... Read through logs, didn't find even one legendary, is this common or am I just missing something?

Bad luck in my opinion. Read through the Junk Log if that keeps happening.
