Hello, does anyone know how to increase an NPC’s TABS and GROUPS up to GROUP3? Like TAB7, TAB8, or more?
I tried setting GROUP3 with TAB7 and TAB8, but when I buy an item from GROUP3 TAB7 SLOT0, the silk deduction is actually based on the price from GROUP2 TAB5 SLOT0. The same happens with GROUP3 TAB8 SLOT0 — it's charging the price from GROUP2 TAB6 SLOT0.
For example, if the item in GROUP3 TAB7 SLOT0 is priced at 150 SILK and the item in GROUP2 TAB5 SLOT0 is 500 SILK, the silk deduction is 500 instead of 150. Similarly, if the item in GROUP3 TAB8 SLOT0 is 250 SILK and the item in GROUP2 TAB6 SLOT0 is 300 SILK, it deducts 300 instead.
Also, after purchasing, it shows a "Cannot Find Target" error. When I teleport or relog, the purchased item turns out to be from GROUP2 TAB5 or TAB6 SLOT0, even though it visually showed GROUP3 TAB7 or TAB8 at the time of purchase.
