Umm I just noticed when I drag my villager over this area south of the food bin, the message that appears is "Is there something buried here?" And she begins digging, but to no avail. Either that or she gives up easily. Now the little contruction graphic, the same one that appears when building a hut or doing whatever, appeared there. But she still gives up really easy. What am I missing? Usually if its a tech it simply says more research is needed. She just leaves though. It doesn't give me a percentage complete either.

I have harvesting, building and science at lvl 3 and the rest at 2.

not missing anything. Keep them at it....and shhhhhhhh don't tell anyone else about this

I have reported the percentage missing and a few other things, so they may work better in the next release
