Description
The current crossover implementation does not consider the restrictions resulting by the grammar. Therefore lots of possible crossover points are invalid and the crossover operation fails or the resulting trees are the same as before (swapping of identical trees). The new crossover operator should check the possible crossover points and overcome these limitations.

Yes you are right, this is not really an issue anymore.

I think this has been resolved with the grammar refactoring? Please check the correctness of the description and improve the description if this problem still exists.
