It is clear that this hack has caused many harm to units and the victims are the poor users who come here for help. I fail to understand what HackMode does that TestMode cannot do (other than screw up units files).
I've ask many times to add a HUGE RED WARNING above the download link to Hack v2.21 but it has never been done. The amount of damaged units keep growing and growing. I believe this hack is simply dangerous and should not be available on a site dedicated to help people.
