After the school is there, how does one "open" it? It keeps saying that everyone thinks the building can be converted, and I got the puzzle school, but is there more? I've got the full research level and have continually dropped ALL of my Master Scientists onto it, but nothing is happening, except they are all wanting to push the rock after I drag them away from the table and drop them repeatedly on the school. The message about "thinks this building could be converted" is still there, so I thought my Master Scientists had to do something again, but nothing works. For that matter, neither will dropping the Master Builder on it.

Help? Do I need any? -- Thanks -- Ella
