Changing Gau's Rages

sure it's not #141?

I have checked 3 times now and it is at 143, unless you count the first entry as 0 or something (which would be 142 then). In-game, I started at the very top left and counted it as "1", then just pressed the right arrow until I reached Brontaur, counting as I went.

also, if the patched ROM is still open-able in FF3usME, can you tell me their two Enemy IDs?

The enemy ID in FF3usME is 132 for Brontaur and 164 for Misfit.

as for the cause, i still don't have a good theory. a mis-editing (i.e. repeating a value) of the list of Enemy IDs used for alphabetization could have a monster in two menu spots, but it wouldn't cause the nonsense of leaping one making you learn another.

To clarify, I am actually not 100% sure if leaping on one monster actually gives you both rages. I made that assumption, because if I use FF3usME to start myself off with just one of those rages using the actor editor, it will give me both of them in-game (using SnesGT and snes9x emulators). I have not physically lept on those monsters in-game, because it would take hours to actually find them on the Veldt to test for real. Maybe I am wrong making that assumption?

Assassin, maybe I can send you a patch? I don't know how to create one yet, but I'm sure I can figure it out. Although I have been modding games for years, this is my first time messing around with FF6 (been playing it since it came out though). I have been working on this particular mod for maybe 6 months now.
