Thanks for checking it for me and for that info. I'm pretty sure that when I built the subdivisions, I just plugged them in and they worked but I haven't tested them on a newer version. I should probably try to stick a note into the files to look for the lib/house directory before using them.
And thanks for the compliment on the elevator. I really love that elevator. I think only the swan in the park beats it for cool stuff I've done but the swan uses such a pile of triggers that it's really a totally different thing.
