Am replaying the game, just going through Goldenwood Cave with Melia.
In the double battle with the 2nd pair of trainers, foe switches out Lombre for Duskull, Melia uses Double-Hit with Buneary on the Duskull which doesn't work because typing, I use Knock-Off on the Duskull and get the below:

OK

Game carries on as usual, Knock Off does hit but yeah
Edit; Error popped up again later in the battle when I went to use Double Kick on Krabby, and they switched it back out for Duskull and it was aimed at by Double Kick. So seems the issue is more for the "not hitting the ghost type". Possibly because both moves are multi-hit moves?
Edit:Edit: SOLVED. WAS A BAD SCRIPTS FILE. AZERY SMELLS.
