[Share] Multisell Quantity Fix

[ethos]

Well as the title says this is a patch to fix the multisell quantity bug when a player is trying to buy

an amount of item that exceeding the slots in his inventory or either exceeding his current weight limit.

 

Example without patch: lets say you got 80 maximum slots and u go to buy 81 or more blessed scrolls from your

custom multisell. Well in my case without this patch after the items was created in your inventory

your client was getting crashed and keep crashing on login until u clear those items from your database.

 

Example with patch: again you got 80 maximum slots and u go to buy 81 or more blessed scrolls from your custom

multisell. You will get a message "Your Inventory is full". or i you try to buy something that u could get more

than 100% weight limit you will get a message "You exceeded your Weight Limit."

 

Tested and working with core L2j Server Interlude rev4709 but im sure this will work in other cores too...

A note that this patch maybe already applied to your core so just ignore it.!

Hope this helps u..!
