Condensing Spell List in Battle

There's a bit of a bug/strange side effect with this patch, Grayshadow's and I have been beating our heads against the wall trying to fix it, let alone figure out wth is going on. Hoping @assassin or anyone else who might know or can spot what is going on can enlighten us about this issue.

The issue is, is for those caam (character acting as monster) battles, where it loads a character (graphics, properties, name etc.) and puts them on the monster side and gives them a monster battle script AI to use -- think Kefka in the Imperial Camp 'battle', or uncontrollable Cyan shortly after that. Normally, without this patch implemented, those caam battles the caam will have infinite MP at their disposal, or rather it's coded to not have any MP deducted when they cast spells. With this patch, however, when a caam casts a spell that costs MP, the 'Need Mp' message pops up and the spell does not cast. Normally in the vanilla game this might not be an issue, because there are very few caam battles and I believe none of them ever cast any spells that cost MP. But with my hack for instance, I have about 5-6 caam battles and they all have spell casting going on, so it's a huge problem for me

So the question is, how is this condensed spell patch causing this issue, and hopefully how to 'fix' it! While the caam does load properties of a character (HP/MP), the MP doesn't seem to be loading and they appear to only have 1 MP when healing with an Ether, so whatever causes the caam to not draw MP when casting a spell might just be broken and not a case of them just not having any MP. Making a spell cost just 1 MP the message still pops up, so I'm guessing it's become broken.

Any help greatly appreciated! I'd really love to use this patch as it saves time scrolling around in the spell menu like a fool and looks much nicer, but as it is I simply could not live with this strange issue.

I should also note that we've run the part of the code we think is responsible for this through the debugger and for all intents it looks like it should NOT be using any MP still, yet the issue persists... I should also note that this issue happens on a clean ROM with this patch, so it's not some issue or confliction just with my hack. I should also note that it doesn't matter what side the caam is on, player or monster.
