This. I've had it happen with the drumsticks. Just clip a little more and go on about your wayI had that happen to a HG Corona Gorda over the weekend. I had 4-5 little tar bubbles at 2/3 into the cigar. It had been stored at 65 and dry boxed for 2 days. Not sure what might have caused it because the rh where I was at was pretty low. I just clipped a bit more off the cap, problem solved.
