You also should add the new starting items to the Auction Hall.
Takes too much effort to check if player have or not those sets. I don't know if I should add those sets, it's been bothering me.
Actually I've been thinking about this...
For example, initially variable 'A' is set to 0. However, after the Azureus Ring is purchased in chapter 1, variable 'A' is set to 1. Then, in chapter 7, the game then checks if variable 'A' is 0 or 1. If it's 0, then Azureus Ring is added to the Auction Hall. If it's 1, then do nothing.
Could that work?
(Again, I'm not very good when it comes to WE triggers, so I'm not sure if that could work. However, if the player has bought the item but then sold/dropped it, then it's obvious that they don't need the item, and there's no need to add the item to the Hall again.)
