Aced Shops

[Ace_V]

That line pertains to the existence of $game_system.acev_shop_limit.  That is a variable that is created when you start a new game.  If you are encountering an issue where it says that variable does not exist, then you are not running this from a new game but an already existing save file.

 My bad! Yes, I did indeed try it from an older save! (Previous one worked on an old save so I assumed this would be OK, too  )
