Temperate buildings to snow theatre, Where be they? Options

[Dudeinabox]

I've currently working on a snow map at the moment and was looking at some other on here and you guys have managed to place buildings such as Rade's roadhouse and port-a-shacks, however in my snow theatre final sun I don't appear to have them, is there anyway of getting them onto there?

Thanks in advance,

Ah Ha! Success! All I have to do is make a new map, save and click new and import that map...didn't know why I didn't think of it before to be honest =\
