I actually found that by myself shortly after getting it. I don't know if I washed it down the drain or it was never there but thank goodness they include an extra one with it.
A little difficult to tell from your pics on the wicking.
Hows your JFC? Tightness wise, moves fairly easy, a little stiff? Have you had it fall over at all, drop it? I'll guarantee it will leak no matter how perfect your wick job if the base is not seated properly during the assembly process.
