Hello folks, I've just recently started playing the game, but there's a problem. I'm at the Vault 15 and can't find the water chip, and what I've read from walkthroughs, that's how it should be. However, I get no message regarding the water chip and I think I've searched every inch of the third, command center floor. Shouldn't the event trigger nearby the blue rocks in the eastern side? Which one of the three places is it, the top, middle or the bottom? Should I use some skill, for instance science?
