The game hangs at the loading screen and it looks like a whole lot of stuff is missing or incomplete.
I just compiled build 29770 using Muton's script v0.7.0.
It's giving me a No .mdx found error for almost every model in the model directory.
ufoconsole.log attached.
When I checked the source files, there are no mdx files there or anywhere else for that matter that I can see. I'm in over my head on this one, but fortunately I'm paranoid enough to have kept my previous installers so I can always go back to those versions.
