[Problem] Graphics & Transformations, a crash-to-desktop odyssey

I've been trying to write a character-transformation buff with custom graphics, but it always crashes the game. Before CotW, it would crash without so much as a message box. Now it comes up with a "instruction at [pointer] referenced memory at [pointer]. Memory could not be 'read'" error.
I'm not sure what's causing this. The Mod Validator throws no errors. The sprites are saved using 8-bit RGB PNGs, as that's what I've seen other mods using. They're also 64x64px (edit: at the moment they're 32x32 because I've been testing things), like many of the official sprites. Does anybody have any idea as to what might be happening?

The spell:

Code:

        <spell name="Angel Form" type="self" icon="skills/placeholder64.png">
 
            <buff useTimer="1" time="10" allowstacking="0" stacksize="1" removable="0" icon="skills/placeholder64.png" smallicon="skills/placeholder32.png" self="1">
 
                <polymorph name="LilAngelGirl"/>
 
            </buff>
 
            </spell>

The monsterDB entry:

Code:

<monDB>
    <monster name="LilAngelGirl" level="1" tiny="0" special="1" taxa="Other">
        <idleSprite left="sprites/angel/angel_idle_l.xml" right="sprites/angel/angel_idle_r.xml" up="sprites/angel/angel_idle_l.xml" down="sprites/angel/angel_idle_r.xml"/>

I'm using photoshop, I'll try resaving them using one of those.

 

Alright, I've converted them all to indexed using mtPaint and it's still throwing the same error. Links in the OP should have updated automatically to the converted image.

 

Can I see your animation .xmls?

 

...okay, I didn't see that link. Your frame delays are crazylow. They should probably reside somewhere between the 50-120 range: right now, your sprite is probably going to cause seizures. That could be what the problem is.

I've also had troubles getting a polymorph with a mod monster to be stable myself, so I don't know if that's indicative of a problem with modded monster polymorphs in general or not.

 

For testing purposes, I've set all the frame durations in all my animation xmls to 150, and yet the crash persists, so I'm guessing it's not just frame length.
