MMMMMagic 2.0

The good news is it's not a problem in the event code. The bad news is there's a problem in the magic learn on recruitment code. Luckily, since it didn't crash at Terra, Celes, Sabin, or Cyan, we know it's the new code we added for Relm and Kappa. I'm betting it's something in the C0 block, I'm going to look there first.

EDIT: After the three NOPs in the Kappa and Relm freespace, there's a JSR to $D613. This is not a vanilla location; it is a learn command set up by MMMMMagic. If you moved it, those two JSRs need to be repointed (this could be the cause of the crash). I'll continue to look for other potential sources.

Code:

EA EA EA 20 13 D6
(occurs twice)

Should point to a block of code that looks like this:
5A 08 48 B9 00 16 E2 30 AA BF 00 00 F3 8F 02 42 00 A9 23 8F 03 42 00 C2 21 A9 89 1A EA EA 6F 16 42 00 85 12 E2 20 7B 68...

I think that might be the problem. Sorry about that. If I worked in ASM instead the pointer could have been a variable and we'd avoid problems like this.
