The biggest change is the ship insertion order for the human players. It starts now by the biggest ship. This way it is impossible to reach a board where is not possible to place the remaining ships (it is possible starting with the smallest ones if there must be an space between them).
If this change is too big, then I'll try to find a solution to detect the "impossible to place more ships" situation and enable a fresh placing restart.
A kWarning() and a TODO in spanish are now gone.

A lot of games with and without several ships, in local against the AI or in remote against myself.
