By 'awhile' do you mean weeks or months?
Some ceegars take forever to dry out, especially if they've been stored really wet.
I bought a box once that seemed almost fireproof. 6 months later, they were finally coming around but would still canoe half way thru and go out near the nub. I think I've had them over a year now at ~62-65 and they finally burn right. Really strange because they weren't bumping the Rh in my box way up either.
