Could be bud rot....be careful smoking it even after it's thoroughly dry...you don't wanna be smokin mold, right? I've had to throw what was once good stuff out before because of this! Yea, it hurts, but no telling what smoking the mold would do... Better off not smoking it at all if you think it's bud rot. I agree, it was not fully dried and cured properly, most likely that's the cause.
