Condensing Spell List in Battle

In vanilla, characters that don't have a Magic command don't get in-battle MP. Could that be the case here?

If so, Lenophis' patch Summon This! contains a fix for that.

However, since that patch contains a lot more, here's the code that's responsible for this:

Code:

C2/53F9: 46 F8        LSR $F8        (Carry gets set if character has Magic/X-Magic command
                                     and at least one spell known, Magic/X-Magic and an
                                     Esper equipped, or if they simply have Lore.)
C2/53FB: B0 0B        BCS $5408
C2/53FD: A3 02        LDA $02,S      (retrieve the X value originally passed to the function.
                                     iow, the index of the party member whose menu is being
                                     examined)
C2/53FF: AA           TAX
C2/5400: C2 20        REP #$20       (Set 16-bit A)
C2/5402: 9E 08 3C     STZ $3C08,X    (zero Current MP)
C2/5405: 9E 30 3C     STZ $3C30,X    (zero Max MP)
C2/5408: 28           PLP
C2/5409: FA           PLX
C2/540A: 60           RTS

If this is the issue, a solution to Nattak's problem could be to give those CAAMs a Magic command, or to kill that branch.

A damn fine guess, but alas I am already using Summon This! and have magic command set on the caam.
