a question regarding reis (dragon) formation sprite on WOTL

[SilverRegret]

anyone know where reis formation sprite is stored on WOTL?
i've tried open UNIT.BIN with FFTEVGRP. but no sign of her formation sprite there..
(the WLDFACE.BIN still got her portrait though..)
i've tried change her palette to white, all (including her formation portrait) works except her sprite (still purple).
