Iron defense glitch?

So today I was training my Scolipede and used the move iron defense, which raises defense by two stages (sharply) But instead of it saying sharply it said “Scolipede’s defense roseDrasticallyI thought nothing of it at first but when I tried using iron defense again it said that Scolipede’s defense couldn’t be raised any higher? I understand that there is a certain move, cotton guard I believe that raises defense by three stages. But why did iron defense max out my defense with just a single usage? Keep in mind this is the first time I used it in that battle. Did I get a sort of critical hit with iron defense? Is such a thing possible?

There is one thing that can cause this occurrence whithout being a glitch. That, is Simple Beam. Most likely, you were batteling a Audino, Elegym or Beeheyem that used Simple Beam on your Pokemon, causing its stat-changes to double. The reason for not being able to use Iron Defense again might be because you already used it and then got hit by Simple Beam, giving it +2 Defense plus 3 Defense= +4 or max Defense.It was certenly not a Critical Hit, only attacks get those.Source: Those stupid Audions are always spamming Simple Beam when I’m training.

Iron Defense raises the Defense by 2 stages.Additionally, even if it was a Drastic raise (+3) it shouldn’t have disallowed you to do it again'. There is no ‘critical’ with any non-damaging moves, so Iron Defense could not have maxed your defense out with one use.You can check the list of Gen V glitches [here][1][1]:http://bulbapedia.bulbagarden.net/wiki/List_of_glitches_in_Generation_VI couldn’t find any glitch to do with Iron Defense :sSo you either 1. misread or 2. discovered a new glich (possible if you were playing on emulator which are alot more dodgy)
