Turn Based Strategy Grids [Released] [Many images]

I picked this up today, and it really doesn’t compile. Is this up to date for 4.7?

Edit: Looks like a lot of ‘cast’ nodes need to be replaced with ‘isvalid’ checks, I think?

Edit #2: Nope, cannot check if valid, since it’s an interface. Cannot cast it to a valid type and check if it’s valid either. Not quite sure what to do with this D:
