I'm using AEoD v5.03, just to follow the rules.
Well, to the point. Last night, while looking through monster decorates (due to a weapon guide I'm writing now that I have free time, you'll see it when it's done), I've noticed that player clone monsters should drop the combat knife, however there's an error that prevents them from doing so.
Where it says: "AEoDDKnifeItem", it should say "AEoDKnifeItem". That seems to solve the problem.
