Tile collision information is saved as an ObjectGroup, however the Tile class does not accurately represent that relationship. Instead it circumvents parsing an ObjectGroup and individually parses the list of objects. This means that saved data about the ObjectGroup (such as name, visibility, offset, color, properties, ect) is not available. You can see this in TmxTile.cpp lines 101-119.
I suggest changing the Tile class to contain an ObjectGroup, rather than a list of Objects. This way all the information for an ObjectGroup will be properly included.
