Hello! As you very well pointed out, I _need_ to just disassemble the faulty whole remnants of the targeting system. The case is the Code Goblins grew into Hobgoblins, and for memory allocation issues, it's way beyond my skills to come up with a regenerated targeting system.
I am deeply sorry for my lack of a valid and fair answer to this matter. Choosing the closest target or casting octo, is the only way. Who knows, as I learn new stuff everyday, this is not a barren field, just one that have to wait for now. But thank you kindly for your enjoyment and patience.
As I type this answer, a new update is being released, with a bunch of more features and many surprises :)
