Well... This problem is strictly on loading. The struct was changed, so it's now
incompatible with the struct stored on your save file. It only produces billions
of warnings because the struct changed was *enemy, and there are hundreds of
*enemy instances...

This is an old problem about struct. When we update the struct on C, the saved
struct becomes incompatible...

So, we need find a way to update the struct om the save file when it's wrong, am
I right?
