Second follow-up:
Vendor has replied. Since I said that I had wiped off the mold and will wait and see, he apologized, said that mold tends to happen in 5-packs where there is no wood to absorb the moisture, and said to contact him again if I needed further help.
I also smoked one day. It was awesome, though a little grassy and young at the start. So thankfully if it is mold it doesn't seem to have caused any damage.
