What is the bug?
In Gen 3 (and only Gen 3), OHKO moves are impacted by an oversight where they do a fixed amount of damage equal to the target's HP stat. While in most cases this oversight is unnoticeable, if the target has a substitute and an HP stat lower than the substitute, then the substitute will not break and will be dealt an amount of damage equal to the Pokemon's current HP stat. This oversight is not currently accounted for in PS!.
Are you able to replicate it? If so, how?
