I would say just keep an eye on them for now, and then worry if it seems to spread to other sticks as time passes...
Anyways, they are probably fakes. Real cubans don't come with mold on them!!
Yup. Only time will tell if the rest of them got the axe. What is your RH% by the way?
The back of the Vino, especially at the bottom, is where the condensation drain is. With summer time here, if you have big temperature fluctuations in the room the Vino is in, you'll find the unit producing condensation, and that's where it gathers.
