I don't know whether these are bugs or features but I've noticed few things :

When trying to decorate javelin it claims that item is not of wood - however only things needed to do javelin is wood. One can decorate staffs thou but I don't know do these carvings live through hardening phase... It seems that they don't as inventory doesn't separate javelins from others although carvings quality on staffs did differ.

Another thing that confuses little is that when asking for directions at village they keep on telling about this village that is on west very near, under kilometer or so. However in most cases there is no village at such location or anywhere near that direction no matter how well I search every hectare.

Sounds to me like they're talking about their own village. It's not so much a bug as it is a lack of the game making them being smart enough to ignore their own village when you ask for directions... a lack of a feature, in other words. It wouldn't be too hard to fix, I think.

I do believe you're right. I'd always considered the little clusters of buildings to be an entire village, but I guess the game considers them to be lots of small ones that just happen to be close together.

I suppose the simple fix would be, when asking for the nearest village, to ignore any results under X distance away.
