SM 4.3.7 Type UI Bug (Page Property) [Fixed]
It has been brought my attention that there is a bug when using maps baked from 3D Models. This would also include any map that uses the Page Property.
When switching the Type property (a Page Property type) from Base Model to Cage Projection, the properties UI are not recreated correctly. I have located the area where this problem is occurring and will post an update here soon.
