Extendcost doesn't work. How can i diagnose what is causing the problem ?

[Wheeze201]

It used to work like a week ago. But now it does not work.

The only table i could remember altering was the items table.
I tried "re-altering" it as in going back how it orginally was and it didn't work.

So what is your advice on where to begin to fix this bug ?

Depending on the core you use, extended costs are handled in different ways. For ArcEmu, the extended costs are handled by a column in the 'vendors' table, and if you haven't changed that at all, I suggest you re-extract your DBC files and replace your existing ones. Any incomplete or incorrect changes that you've done to the extended cost DBC file will cause the server to load it incorrectly without warning you.

Did you update the Rev? In 27XX the structure of the DB changed again, Ima go check now for you.

The extendedcostid refers to an id found in a DBC file. This DBC file can have various values assigned as an 'extended cost'. If the cost is to be an item, the itemid can be found there. it could be that you messed up some id's in the item table meaning it assigns the wrong item as a cost (or it doesn't assign anything at all, if the id doesn't exist anymore).
