Hey yep, it worked in build mode! ^^ Glad someone mentioned that.

I downloaded the collection file, put it in collections, and of course, the community wedding hack, and put that in downloads... the arch shows up in the collections, but it makes the 'boop' noise it makes when it can't do something.. and I can't put the arch in the lot. I checked to make sure they were in the right folders and everything, I'm not sure why I can't put the arch there..
