Brownie effect on cob wall

Hello everyone!
Either in Ianto's book or somebody elses they say "you don't want to smooth the vertical surface of the cob with each lift, because it will prevent good drying". So i i did smooth it with the trowel - it is actually eliminates drastically the cutting - and i like that fact very much We have very hot weather here and there is the wind at my building site - so everything dries very good, i lift every day 10 cm of cob. BUT! Yesterday i decided to cut out a cap for the window and found out that i have an approximately 2 cm of very dry cob on the sides of the wall and wet cob inside, plus it has a nasty rotten smell!
So, i say to myself, it's normal for cob i guess - it can't dry entirely in several days and it's logical that drying process moves from outside towards inside. But smell!

So i got a little paranoid

What the professionals would say on the matter?
Thank you in advance guys

here what i have built

Sorry for this not such a quick answer
Well, i just let it go. I thought about it and decided that the drying process won't go that fast and similair in every layer of cob, so i considered it kind of normal

I must say since then the wall grew a lot and I already have put some beams for the green roof; walls survived a lot of rain being uncovered - and everything is fine!

The local semi-wild cat, which friends of mine named Linda Smiley came recently with the inspection of the wall and beams
