Clogging

Yup, that's tar!
My experience like that resulted in me cutting the cigar with a guillotine cutter and it smoked much better after that.

Same here!

I foind this happens to me if it's humid outside.

I simply cut it and get back to smoking.

Agreed!
I also only experienced this when I used a punch vs a guillotine.
I'm guessing since the punch restricts the draw more so than any other cut. As a result, when I do use a punch I will use the (for lack of a better description) "figure 8" punch. I guess a larger punch may also work.
