List of changes
- When buying an item, the confirmation gump will tell you what type of item it is. Whether it's a weapon, armor, ethereal, deco, resource, tool.... That will hopefully clear up future issues where someone thinks they're buying something, but actually gets a different thing.
- Sales will no longer be final in absolute terms, but staff might undo a trade if it seems misleading. In case of misleading sales, it's then possible to review what the system description was, and if it was incorrect, the trade will be reversed. (along with a correction to the system-generated-description, so that the same kind of item isn't an issue in the future). And with that corrected description, the item can be placed on the vendor again.
- Vendors are getting an anti-raid feature. It will be possible to limit how many items a single player can buy in a certain timespan (e.g. 3 items in 24 hours). This has been an issue since the dawn of time, where some want to make items priced for newbies, or make a sale to advertise the vendor or the shop. What usually happens is that someone out there is very happy to get a load of cheap stuff, which they sell on their own vendor. This feature will be disabled by default, and customizable by vendor owner/coowners. An alternative idea was to mark items so that they can't be re-sold for a certain duration (sort of like temporary account binding) but this is a simpler solution, both in terms of coding and with less confusion with players wondering why this item is now account bound.
- Vendors will display their co-owners publicly. So if there's any vendor that you not just co-own, but are a "shadow owner" of, be sure to make proper arrangements to keep your identity a secret

- Some items to be restricted from selling on vendors: skill balls (character bound ones), and certains types of special tubs. Items that are basically account-bound or character-bound, but not using the standard account-bound system.
