I decided to upgrade the last 2 categories to Level 3 so now my guys will probably live forever. The researchers are at loose ends now so they're wandering around, looking at the cactus, trying to move the boulder, exercising or just doing nothing. I left it running all day today, not knowing that I wouldn't get back to it, and just turned in on now. Nothing has happened!
I have 61 villagers so I marked some of the females for breeding so we'll see what happens. Will the GC show up after puzzle 9 or do I have to figure out 10 somehow before it shows up?
