This could just be a bole, arrow, or balance you just won't see for two or three encounters. At all.
Consider the fact that your chance of not drawing a given card is 5 in 6. To not draw a card in say, 3 draws is (5/6)^3 - which is about a 57% chance.
(5/6)^19 is ~3%.
These dry spells happened 14 times during the test - which is pretty dang crazy for something that only has around 3% chance of happening. Yesterday I apparently should have been playing the lottery.
