would you mind maybe posting Direction file (maybe even Tile file)?

 

also.. for the hell of it.. could you try adding a default action inside the default constructor (so when you call it, it actually instantiates an 'empty' tile) and see if that helps?

 

Although this might be due to empty constructors inside Direction or even Tile file.
