Thanks I figured it was the construction skill that was making them want to clear because my "pure scientist" (I haven't had them do anything else but research) types wouldn't touch the creek with a 10 foot pole! Hehe. I have two with high construction skill from building huts that are on a break and were researching/collecting food as I get more tech points. Hopefully they'll start un-blocking on their own once I get the food back up.

So much to do for these little villagers - so little time!!
