The code that seems to be causing problems is:

STAR 0
ITEM it_decoder
END STAR

STAR 1
ITEM it_encbank
END STAR

CONDITION 0
TYPE haveitem
STR0 it_decoder
END CONDITION

CONDITION 1
TYPE haveitem
STR0 it_encbank
END CONDITION

PAGE 1
REQ0 0
REQ1 1
DISP 1
ACTN popup endquest
TITL Databank Decryption
GFXP items/bank.png
TEXT [Blah blah blah. Spoilers not listed.]
REMV it_encbank
REMV it_decoder
TIME 2
ITEM it_membank
END PAGE

Hmmm... I wonder if the item side of things could have anything to do with this.
