Eh, it still doesn't work, except now I don't get an error, it just sorta overlooks it, and delets the event, so to speak.
Example:
Starts on Aeion Legend
event
>Conditional branch: script: $game.difficulty == "Aeion Legend" (or something like that, whatever zeriab said, lol)
>Change level- Zan Vossmore +4
>Change skills Add Cure
>Else Handler
>
