JII Version 4.2: Fixed?

I believe that I have fixed the problems that were causing the missing buildings in the web simulation.  It was apparently the result of some corrupted geometry in the Sketchup models.  In the process of cleaning that up, I managed to remove a lot of unnecessary parts and simplify the models.  It kind of needed to happen anyway.  I also derived a method for testing the issues at home instead of waiting to see the results the next day at work.  Turns out that the missing buildings only showed up on Windows XP machines.  Yay for compatibility mode.  Please let me know if any of you have continuing issues, but I think I got this one.
Oh... and I accidentally erased the escalators in the lobby.  Maybe when I restore them, I'll figure out how to make them work too.  :-)

Technical Problems

There have been some mysterious issues with the web simulation since the last update.  For many people, some of the buildings are missing and falling off the face of the Earth is common.  And I know the simulation won't load at all for others.  Sorry about that.  :-(

I probably should have said something about this sooner, but I honestly thought I'd fix the issue long before now.  Not so much...

I think I have tracked down the issue and hope to have it fixed shortly.  Unfortunately, everything looks perfect on my home computer so I don't know if the fixes worked until I test it out the next morning at work.  It's not the most optimal troubleshooting arrangement.  I'll get it though.  I promise.

Thanks for you patience and the helpful feedback several of you have given me.  :-)
