Six months should not affect a cigar adversely. That short a period is only rest, aging requires years, some say decades. Often "House" cigars are short batch cigars and the blends are very inconsistent. But I have also had cigars from the same box or bundle show totally different tastes, most recently with two Casa Magna's. Two of us lit up smokes from the same bundle at an event, one was spicy and full bodied while the other was bland and tasteless.
