      May 11, 2026: The Red Sun still prevails. &lt;br/&gt;&lt;br/&gt;However, I noticed something odd. Either this is purely coincidence, or the exploit has less reliability now (?). On a freshly booted system, it works 100%, but after a couple minutes of runtime, it seems that it doesn&amp;#39;t always win the race condition (or it takes longer than the usual ~10 seconds).
