Dissapearing guys is a utility featuring the Heavy Swordsman, a unit that occasionally disappears from view.
This utility has no use. The Heavy Swordsman is a secret to few, and the utility shows no use for them. There are no instructions, no triggers, nothing to show what use the units have. This utility might have salvaged a point or two if some instructions were written.
In conclusion, this utility simply has a unit most people know about, and shows nothing new, with no creativity. This should not have been uploaded to the Blacksmith.
