I was up to 65 villagers and then the locusts (I think) made everyone sick and when I came back to the game, I only had 4 survivors (one girl). No big deal... time to breed again.

1] I now have 23 villagers, but I can't get anyone to do any construction. I have the ruins rebuilt, three huts, and the creek cleared out.

2] How do I move the big boulder? What type of specialist should I sent to investigate?

3] Now that I have maxed out on what my tech points can purchase, is there a reason to still have people research? Are they the ones who help me figure out the last five puzzles?

4] I have those two fields on the right side that are not used. Who should I send over there? (I found the graveyard already).

Thanks!
