Aging badly?

Anyone ever had a smoke age badly? I had a Casa Torano, The last one from a box I bought a long time ago thats been in the humi for almost 4 years now and It was horrible! The smooth mildness its known for went to hell in a handbasket.

So I pulled out one with 3 years on it and it was bad. Pulled out one that was in a new shipment with maybe 4 months on it, Its perfect.

Anyone else ever have a smoke that aged badly consistantly?
