Yes this was discussed in the first pages of this thread, it conflicts with Assassin's alphabetical rage patch. It's only a free space conflict which can easily be remedied by changing freespace lines in the ASM file.
!freespace_C2_0 = $C2A65A
!freespace_C2_1 = $C2FAB0
!freespace_C2_0 = $C2A65A
!freespace_C2_1 = $C2FAB0
