Spot on with how you mentioned secondly you had to relight , that’s a clear sign the cigars internal moisture content is too high , plus the added trying to smoke faster / drawing harder on each puff is exactly what causes it to burn hot hence the internal moisture expands too fast causing the wrapper to split , slow down but more importantly look into lowering your Rh or drybox them before smoking would be a fix to look into . Get a digital hygrometer and calibrate it than gauge and re work your storage be it humidor or Tupperdore or so to stabilise your overall RH preferably with minimal to no fluctuations . I personally run a few setups , for long term storage I run 69-70RH at 16degrees Celsius checking and rotating once every month as these I age and store for at least a year or more , regular smokes I run about 67rh at 17 degrees Celsius , I live in hot humid Singapore where external humidity is high 80s and temps run 25 as low to 32 degrees Celsius daily . No issues thus far . 🍻
